# Loops/With multiple ranges

Loops/With multiple ranges
You are encouraged to solve this task according to the task description, using any language you may know.

Some languages allow multiple loop ranges, such as the PL/I example (snippet) below.

<lang pli> /* all variables are DECLARED as integers. */

```         prod=  1;                    /*start with a product of unity.           */
sum=  0;                    /*  "     "  "   sum    " zero.            */
x= +5;
y= -5;
z= -2;
one=  1;
three=  3;
seven=  7;
/*(below)  **  is exponentiation:  4**3=64 */
do j=   -three  to     3**3        by three   ,
-seven  to   +seven        by   x     ,
555  to      550 - y               ,
22  to      -28        by -three  ,
1927  to     1939                   ,
x  to        y        by   z     ,
11**x  to    11**x + one;
/* ABS(n) = absolute value*/
sum= sum + abs(j);                           /*add absolute value of J.*/
if abs(prod)<2**27 & j¬=0  then prod=prod*j; /*PROD is small enough & J*/
end;                                         /*not 0, then multiply it.*/
/*SUM and PROD are used for verification of J incrementation.*/
display (' sum= ' ||  sum);                    /*display strings to term.*/
display ('prod= ' || prod);                    /*   "       "     "   "  */</lang>
```

Simulate/translate the above PL/I program snippet as best as possible in your language,   with particular emphasis on the   do   loop construct.

The   do   index must be incremented/decremented in the same order shown.

If feasible, add commas to the two output numbers (being displayed).

Show all output here. <lang> A simple PL/I DO loop (incrementing or decrementing) has the construct of:

```           DO variable = start_expression    {TO ending_expression]       {BY increment_expression} ;
---or---
DO variable = start_expression    {BY increment_expression}    {TO ending_expression]    ;
```
```     where it is understood that all expressions will have a value.  The  variable  is normally a
scaler variable,  but need not be  (but for this task, all variables and expressions are declared
to be scaler integers).   If the   BY   expression is omitted,  a   BY   value of unity is used.
All expressions are evaluated before the   DO   loop is executed,  and those values are used
throughout the   DO   loop execution   (even though, for instance,  the value of   Z   may be
changed within the   DO   loop.    This isn't the case here for this task.
```
```     A multiple-range   DO   loop can be constructed by using a comma (,) to separate additional ranges
(the use of multiple   TO   and/or   BY   keywords).     This is the construct used in this task.

There are other forms of   DO   loops in PL/I involving the  WHILE  clause,  but those won't be
needed here.    DO  loops without a   TO   clause might need a   WHILE   clause  or some other
means of exiting the loop  (such as  LEAVE,  RETURN,  SIGNAL,  GOTO,  or  STOP),  or some other
(possible error) condition that causes transfer of control outside the  DO  loop.

Also, in PL/I, the check if the   DO   loop index value is outside the range is made at the
"head"  (start)  of the   DO  loop,  so it's possible that the   DO   loop isn't executed,  but
that isn't the case for any of the ranges used in this task.
```
```     In the example above, the clause:                    x    to y       by z
will cause the variable   J   to have to following values  (in this order):  5  3  1  -1  -3  -5
```
```     In the example above, the clause:                 -seven  to +seven  by x
will cause the variable   J   to have to following values  (in this order):  -7  -2   3  </lang>
```

V ss = String(s) V ps = String(prod) V m = max(ss.len, ps.len) print(‘ sum = ’ss.rjust(m)) print(‘prod = ’ps.rjust(m))</lang>

## AutoHotkey

As with most of the other languages, AutoHotkey doesn't support multiple loop ranges, so a workaround function is used instead. <lang AutoHotkey>for_J(doFunction, start, stop, step:=1){ j := start while (j<=stop) && (start<=stop) && (step>0) %doFunction%(j), j+=step while (j>=stop) && (start>stop) && (step<0) %doFunction%(j), j+=step }</lang> Examples:<lang AutoHotkey>prod := 1 sum := 0 x := +5 y := -5 z := -2 one := 1 three := 3 seven := 7

for_J("doTHis", -three, 3**3, three) for_J("doTHis", -seven, +seven, x) for_J("doTHis", 555, 550-y) for_J("doTHis", 22, -28, -three) for_J("doTHis", 1927, 1939) for_J("doTHis", x, y, z) for_J("doTHis", 11**x, 11**x+one)

## C#

Multiple ranges don't exist in C# out-of-the-box but it is easy to make something. <lang csharp>using System; using System.Collections.Generic; using System.Linq;

public static class LoopsWithMultipleRanges {

```   public static void Main() {

int y = -5;
int z = -2;

sum += Math.Abs(j);
if (Math.Abs(prod) < (1 << 27) && j != 0) prod *= j;
}
Console.WriteLine(\$" sum = {sum:N0}");
Console.WriteLine(\$"prod = {prod:N0}");
}
```
```   static IEnumerable<int> For(int start, int end, int by = 1) {

## C++

Works with: C++11

C++ doesn't natively support multiple ranges, but we can simulate that using a list and then iterating over the values in that list.

<lang cpp>#include <iostream>

1. include <cmath>
2. include <vector>

using std::abs; using std::cout; using std::pow; using std::vector;

int main() {

```   int prod  = 1,
sum   = 0,
x     = 5,
y     = -5,
z     = -2,
one   = 1,
three = 3,
seven = 7;
```
```   auto summingValues = vector<int>{};
```
```   for(int n = -three; n <= pow(3, 3); n += three)
summingValues.push_back(n);
for(int n = -seven; n <= seven; n += x)
summingValues.push_back(n);
for(int n = 555; n <= 550 - y; ++n)
summingValues.push_back(n);
for(int n = 22; n >= -28; n -= three)
summingValues.push_back(n);
for(int n = 1927; n <= 1939; ++n)
summingValues.push_back(n);
for(int n = x; n >= y; n += z)
summingValues.push_back(n);
for(int n = pow(11, x); n <= pow(11, x) + one; ++n)
summingValues.push_back(n);
```
```   for(auto j : summingValues)
{
sum += abs(j);
if(abs(prod) < pow(2, 27) && j != 0)
prod *= j;
}
```
```   cout << "sum = " << sum << "\n";
cout << "prod = " << prod << "\n";
```

}</lang>

Output:
```sum = 348173
prod = -793618560```

## Common Lisp

Using raw code and DO iterator <lang lisp> (let ((prod 1) ; Initialize aggregator

```     (sum 0)
(x 5)				; Initialize variables
(y -5)
(z -2)
(one 1)
(three 3)
(seven 7))
```
``` (flet ((loop-body (j)			; Set the loop function
```

(incf sum (abs j)) (if (and (< (abs prod) (expt 2 27)) (/= j 0)) (setf prod (* prod j)))))

```   (do ((i (- three) (incf i three)))	; Just a serie of individual loops
```

((> i (expt 3 3)))

```     (loop-body i))
(do ((i (- seven) (incf i x)))
```

((> i seven))

```     (loop-body i))
(do ((i 555 (incf i -1)))
```

((< i (- 550 y)))

```     (loop-body i))
(do ((i 22 (incf i (- three))))
```

((< i -28))

```     (loop-body i))
(do ((i 1927 (incf i)))
```

((> i 1939))

```     (loop-body i))
(do ((i x (incf i z)))
```

((< i y))

```     (loop-body i))
(do ((i (expt 11 x) (incf i)))
```

((> i (+ (expt 11 x) one)))

```     (loop-body i)))
```
``` (format t "~&sum  = ~14<~:d~>" sum)
(format t "~&prod = ~14<~:d~>" prod))
```

</lang> or with loop ranges and increments as list to dolist <lang lisp> (let ((prod 1)

```     (sum 0)
(x 5)
(y -5)
(z -2)
(one 1)
(three 3)
(seven 7))
```
``` (flet ((loop-body (j)			; Set the loop function
```

(incf sum (abs j)) (if (and (< (abs prod) (expt 2 27)) (/= j 0)) (setf prod (* prod j)))))

```   (dolist (lst `((,(- three) ,(expt 3 3) ,three)
```

(,(- seven) ,seven ,x) (555 ,(- 550 y) -1) (22 -28 ,(- three)) (1927 1939 1) (,x ,y ,z) (,(expt 11 x) ,(+ (expt 11 x) one) 1)))

```     (do ((i (car lst) (incf i (caddr lst))))
```

((if (plusp (caddr lst)) (> i (cadr lst)) (< i (cadr lst)))) (loop-body i))))

``` (format t "~&sum  = ~14<~:d~>" sum)
(format t "~&prod = ~14<~:d~>" prod))
```

</lang>

Output:
```sum  =        348,173
prod =   -793,618,560
```

## Eiffel

Eiffel does not support multiple ranges in the same fashion as PL/I. However, it does have an across loop, which does the trick, together with an inline agent (lambda function). <lang eiffel> class APPLICATION

create make

feature

prod, sum, x, y, z, one, three, seven: INTEGER

make local process: PROCEDURE do prod := 1; x := 5; y := -5; z := -2; one := 1; three := 3; seven := 7 process := (agent (j: INTEGER) do print (j.out + ", ") sum := sum + j.abs if prod.abs < 2^27 and j /= 0 then prod := prod * j end end)

across (-three |..| (3^3).truncated_to_integer).new_cursor + (three - 1) as ic loop process.call (ic.item) end across (-seven |..| seven).new_cursor + (x - 1) as ic loop process.call (ic.item) end across 555 |..| (550 - y) as ic loop process.call (ic.item) end across (-26 |..| 22).new_cursor + (three - 1) as ic loop process.call (ic.item) end across 1927 |..| 1939 as ic loop process.call (ic.item) end across (y |..| x).new_cursor + (-z - 1) as ic loop process.call (ic.item) end across (11^x).truncated_to_integer |..| ((11^x).truncated_to_integer + 1) as ic loop process.call (ic.item) end

print ("%N") print ("sum = " + sum.out + "%N") -- sum = 348,173 print ("prod = " + prod.out + "%N") -- prod = -793,618,560 end

end </lang>

Alternatively, there is the "symbolic form" of the across loop, which modifies the code as follows:

<lang eiffel> class APPLICATION

## Groovy

Solution: <lang groovy>def (prod, sum, x, y, z, one, three, seven) = [1, 0, +5, -5, -2, 1, 3, 7]

for (

```   j in (
((-three) .. (3**3)       ).step(three)
+ ((-seven) .. (+seven)     ).step(x)
+ (555      .. (550-y)      )
+ (22       .. (-28)        ).step(three)    // This is correct!
// Groovy interprets positive step size as stride through the LIST ELEMENTS as ordered
// and negative step size as stride through the REVERSED LIST ELEMENTS as ordered
//   so step(-3) gives:   -28, -25, -22, ... ,  20
//   while step(3) gives:  22,  19,  16, ... , -26
+ (1927     .. 1939         )
+ (x        .. y            ).step(z)
+ (11**x    .. (11**x + one))
)
```

) {

```   sum = sum + j.abs()
if ( prod.abs() < 2**27 && j != 0) prod *= j
```

}

println " sum= \${sum}" println "prod= \${prod}"</lang>

Output:

``` sum= 348177
prod= -793618560```

Haskell does not have loops. Programmers use either explicit recursion or recursive schemes (folds or unfolds) for looping. The following code mimics the PL/1 example using composition of left folds in order to handle multiple ranges:

<lang haskell>loop :: (b -> a -> b) -> b -> a -> b loop = foldl . foldl

example = let

``` x = 5
y = -5
z = -2
one = 1
three = 3
seven = 7
in
loop
-- body
(
\(sum, prod) j ->
(
sum + abs j,
if abs prod < 2^27 && j /= 0
then prod * j else prod
)
)
-- initial state
(0, 1)
-- ranges
[ [-three, -three + three .. 3^3]
, [-seven, -seven + x .. seven]
, [555 .. 550 - y]
, [22, 22 - three .. -28]
, [1927 .. 1939]
, [x, x + z .. y]
, [11^x ..  11^x + one] ]</lang>
```

## J

J uses the names x, y, m, n, u, v to pass arguments into explicit definitions. Treating these as reserved names is reasonable practice. Originally these had been x. , y. etceteras however the dots must have been deemed "noisy".

We've passed the range list argument literally for evaluation in local scope. Verb f evaluates and concatenates the ranges, then perhaps the ensuing for. loop looks somewhat like familiar code.

<lang j> NB. http://rosettacode.org/wiki/Loops/Wrong_ranges#J NB. define range as a linear polynomial start =: 0&{ stop =: 1&{ increment =: 2&{ :: 1: NB. on error use 1 range =: (start , increment) p. [: i. [: >: [: <. (stop - start) % increment

f =: 3 :0

```input =. y
'prod sum x y z one three seven' =. 1 0 5 _5 _2 1 3 7
J =. ([: ; range&.>) ". input
for_j. J do.
sum =. sum + | j
if. ((|prod)<2^27) *. (0 ~: j) do.
prod =. prod * j
end.
end.
sum , prod
```

) </lang>

```   ] A =: f '((-three), (3^3), three); ((-seven),seven,x); (555 , 550-y); (22 _28, -three); 1927 1939; (x,y,z); (0 1 + 11^x)'

## Java

Java does not support multiple ranges. Use list to simulate multiple ranges. Accumulate values in a list, then iterate over the list.

With Java 8, streams are available. Streams can be concatenated. However, the Java 9 feature `takeWhile` is important to this task to specify the iteration limit.

Maintain formatting similar to the original code.

<lang java> import java.util.ArrayList; import java.util.List;

public class LoopsWithMultipleRanges {

```   private static long sum = 0;
private static long prod = 1;

public static void main(String[] args) {
long x = 5;
long y = -5;
long z = -2;
long one = 1;
long three = 3;
long seven = 7;

List<Long> jList = new ArrayList<>();
for ( long j = -three     ; j <= pow(3, 3)        ; j += three )  jList.add(j);
for ( long j = -seven     ; j <= seven            ; j += x )      jList.add(j);
for ( long j = 555        ; j <= 550-y            ; j += 1 )      jList.add(j);
for ( long j = 22         ; j >= -28              ; j += -three ) jList.add(j);
for ( long j = 1927       ; j <= 1939             ; j += 1 )      jList.add(j);
for ( long j = x          ; j >= y                ; j += z )      jList.add(j);
for ( long j = pow(11, x) ; j <= pow(11, x) + one ; j += 1 )      jList.add(j);
```
```       List<Long> prodList = new ArrayList<>();
for ( long j : jList ) {
sum += Math.abs(j);
if ( Math.abs(prod) < pow(2, 27) && j != 0 ) {
prod *= j;
}
}

System.out.printf(" sum        = %,d%n", sum);
System.out.printf("prod        = %,d%n", prod);
System.out.printf("j values    = %s%n", jList);
System.out.printf("prod values = %s%n", prodList);
}

private static long pow(long base, long exponent) {
return (long) Math.pow(base, exponent);
}

```

} </lang>

Output:
``` sum        = 348,173

## jq

Works with: jq

Works with gojq, the Go implementation of jq

jq is stream-oriented, and so the "multiple ranges" feature comes for free, that is, it just involves stream concatenation with the "," operator.

The only wrinkle is that jq's `range` filters exclude the "right-hand" limit; to facilitate comparison with the PL/I code, the adjustment (e.g. "1 + ...") has been made explicit.

Since the only variables that are updated within the body of the loop are "sum" and "prod", the others could be defined as constants (i.e. as \$-variables), but again to facilitate comparison with the PL/I code, this has not been done.

<lang jq>

1. If using gojq, one may want to preserve integer precision, so:

def power(\$b): . as \$in | reduce range(0;\$b) as \$i (1; . * \$in);

{ prod: 1, # start with a product of unity.

``` sum:  0,                             #  henceforth skip redundant comments.
x:  5,
y: -5,
z: -2,
one:  1,
three: 3,
seven: 7 }
```

| .x as \$x | reduce (range(-.three; 1 + 3|power(3); .three),

```         range(-.seven; 1 + .seven;     .x),
range(    555; 1 +  550 - .y),
range(     22; -1 -28;          -.three),
range(1927   ; 1 + 1939),
range(.x     ; .y;              .z),
range(11|power(\$x); 1 + ( 11 | power(\$x)) + .one)) as \$j (.;
.sum += (\$j|length)                         # add absolute value of \$j (!)
| if (.prod|length) < (2|power(27)) and \$j != 0
```

then .prod *= \$j else . end ) | "sum= \(.sum)",

``` "prod= \(.prod)"
```

</lang>

Output:
```sum=  348726
prod= -793618560
```

## M2000 Interpreter

Using lambda functions and a final While End While to perform a multiple range.

Values by default are double, but we can make them Long (32 bit integer), or Decimal or Currency or single (prod for single has less accuracy here), but not integer (16 bit) because we get overflow.

In M2000 expressions can change numeric type to hold the produced value. Variables take once the type, so we get overflow if we pass a value frome an expression which can't convert to variable's type.

<lang M2000 Interpreter>Module MultipleLoop { def long prod=1, sum=0, x=+5,y=-5, z=-2, one=1, three=3, seven=7, j Range=lambda (a, b, c=1) ->{ =lambda a, b, c (&f)-> { if compare(a,b)=sgn(c) then =false else =true: f=a: a+=c } } MultipleRange=Lambda -> { a=array([]) ' convert stack items in current stack [] to an array of items =lambda a, k=0 (&f) ->{ do : if k<len(a) Else exit if a#eval(k, &f) then =true: exit k++ : always } } Exec=MultipleRange(Range(-three, 3**3, three), Range(-seven, +seven, x), Range(555, 550-y), Range(22, -28, -three), Range(1927, 1939), Range(x,y,z), Range(11**x, 11**x+one)) j=0 while Exec(&j) sum+=abs(j) if abs(prod) < 2^27 And j <> 0 then prod*=j End While

## Nim

Nim doesn’t provide loops with multiple ranges. There are several ways to translate the PL/1 program: using a sequence of for loops, using a sequence of while loops, using an iterator and, probably, too, some way using macros.

### Using a sequence of loops

This solution is the obvious one, but it supposes that the direction of the loop is known (i.e. the sign of the step is known) as we have to choose between iterators “countup” and “countdown”. Using this method, the PL/1 example can be translated the following way:

<lang Nim> import math, strutils

var

``` prod = 1
sum = 0
```

let

``` x = +5
y = -5
z = -2
one = 1
three = 3
seven = 7
```

proc body(j: int) =

``` sum += abs(j)
if abs(prod) < 2^27 and j != 0: prod *= j
```

for j in countup(-three, 3^3, three): body(j) for j in countup(-seven, seven, x): body(j) for j in countup(555, 550 - y): body(j) for j in countdown(22, -28, three): body(j) for j in countup(1927, 1939): body(j) for j in countdown(x, y, -z): body(j) for j in countup(11^x, 11^x + one): body(j)

let s = (\$sum).insertSep(',') let p = (\$prod).insertSep(',') let m = max(s.len, p.len) echo " sum = ", s.align(m) echo "prod = ", p.align(m)</lang>

Note that for “countdown” we must change the sign of the step to insure that it is positive.

Output:
``` sum =      348,173
prod = -793,618,560```

### Using an iterator

If the sign of the step is not known (or may vary), it is no longer possible to use the previous method. One could use a while loop but it seems better to use an iterator.

<lang Nim>import math, strutils

var

``` prod = 1
sum = 0
```

let

``` x = +5
y = -5
z = -2
one = 1
three = 3
seven = 7
```

type Range = tuple[first, last, step: int]

func initRange(first, last, step = 1): Range = (first, last, step)

iterator loop(ranges: varargs[Range]): int =

``` for r in ranges:
if r.step > 0:
for i in countup(r.first, r.last, r.step):
yield i
elif r.step < 0:
for i in countdown(r.first, r.last, -r.step):
yield i
else:
raise newException(ValueError, "step cannot be zero")
```

for j in loop(initRange(-three, 3^3, three),

```             initRange(-seven, seven, x),
initRange(555, 550 - y),
initRange(22, -28, three),
initRange(1927, 1939),
initRange(x, y, -z),
initRange(11^x, 11^x + one)):
sum += abs(j)
if abs(prod) < 2^27 and j != 0: prod *= j
```

let s = (\$sum).insertSep(',') let p = (\$prod).insertSep(',') let m = max(s.len, p.len) echo " sum = ", s.align(m) echo "prod = ", p.align(m)</lang>

Note that we have defined a function “initRange” to create the ranges. This is needed to make the step optional. If we suppressed this requirement (i.e. we required the step to be always specified), we could get ride of “initRange” and write the loop this way:

<lang Nim>for j in loop((-three, 3^3, three),

```             (-seven, seven, x),
(555, 550 - y),
(22, -28, three),
(1927, 1939, 1),
(x, y, -z),
(11^x, 11^x + one)):
sum += abs(j)
if abs(prod) < 2^27 and j != 0: prod *= j</lang>
```

<lang perl>use constant one => 1; use constant three => 3; use constant seven => 7; use constant x => 5; use constant yy => -5; # 'y' conflicts with use as equivalent to 'tr' operator (a carry-over from 'sed') use constant z => -2;

## Prolog

Prolog does not have the richness of some other languages where it comes to loops, variables and the like, but does have some rather interesting features such as difference lists and backtracking for generating solutions. <lang prolog>for(Lo,Hi,Step,Lo)  :- Step>0, Lo=<Hi. for(Lo,Hi,Step,Val) :- Step>0, plus(Lo,Step,V), V=<Hi, !, for(V,Hi,Step,Val). for(Hi,Lo,Step,Hi)  :- Step<0, Lo=<Hi. for(Hi,Lo,Step,Val) :- Step<0, plus(Hi,Step,V), Lo=<V, !, for(V,Lo,Step,Val).

sym(x,5).  % symbolic lookups for values sym(y,-5). sym(z,-2). sym(one,1). sym(three,3). sym(seven,7).

## Raku

(formerly Perl 6)

This task is really conflating two separate things, (at least in Raku). Sequences and loops are two different concepts and may be considered / implemented separately from each other.

Yes, you can generate a sequence with a loop, and a loop can use a sequence for an iteration value, but the two are somewhat orthogonal and don't necessarily overlap.

Sequences are first class objects in Raku. You can (and typically do) generate a sequence using the (appropriately enough) sequence operator and can assign it to a variable and/or pass it as a parameter; the entire sequence, not just it's individual values. It may be used in a looping construct, but it is not necessary to do so.

Various looping constructs often do use sequences as their iterator but not exclusively, possibly not even in the majority.

Displaying the j sequence as well since it isn't very large.

<lang perl6>sub comma { (\$^i < 0 ?? '-' !! ) ~ \$i.abs.flip.comb(3).join(',').flip }

my \x = 5; my \y = -5; my \z = -2; my \one = 1; my \three = 3; my \seven = 7;

my \$j = flat

``` ( -three, *+three … 3³         ),
( -seven, *+x     …^ * > seven ),
( 555   .. 550 - y             ),
( 22,     *-three …^ * < -28   ),
( 1927  .. 1939                ),
( x,      *+z     …^ * < y     ),
( 11**x .. 11**x + one         );
```

put 'j sequence: ', \$j; put ' Sum: ', comma [+] \$j».abs; put ' Product: ', comma ([\*] \$j.grep: so +*).first: *.abs > 2²⁷;

1. Or, an alternate method for generating the 'j' sequence, employing user-defined
2. operators to preserve the 'X to Y by Z' layout of the example code.
3. Note that these operators will only work for monotonic sequences.

## Red

As "to" has another meaning in Red, we name "->" the range operator. <lang>Red ["For loop with multiple ranges"]

->: make op! function [start end][

```   res: copy []
repeat n 1 + absolute to-integer end - start [
append res start + either start > end [1 - n][n - 1]
]
```

] by: make op! function [s w] [extract s absolute w]

for: function ['word ranges body][

```   inp: copy []
foreach c reduce ranges [append inp c]
foreach i inp [set word i do body]
```

]

```prod:  1
sum:  0
x: +5
y: -5
z: -2
one:  1
```

three: 3 seven: 7

for j [

```   0 - three -> (3 ** 3)   by three
0 - seven -> seven      by x
555   -> (550 - y)
22    -> -28        by (0 - three)
1927  -> 1939
x     -> y          by z
11 ** x   -> (11 ** x + one)
```

] [

```   sum: sum + absolute j;
if all [(absolute prod) < power 2 27 j <> 0] [prod: prod * j]
```

] print ["sum: " sum "^/prod:" prod]</lang>

Output:
```sum:  348173

## REXX

Programming note:   the (sympathetic) trailing semicolons (;) after each REXX statement are optional,   they are only there to mimic what the PL/I language requires after each statement.

The technique used by this REXX version is to "break up" the various   do   iterating clauses (ranges) into separate   do   loops,   and have them invoke a subroutine to perform the actual computations. <lang rexx>/*REXX program emulates a multiple─range DO loop (all variables can be any numbers). */

```prod=  1;
sum=  0;
x= +5;
y= -5;
z= -2;
one=  1;
```

three= 3; seven= 7;

```     do j=   -three  to      3**3      by three  ;      call meat;      end;
do j=   -seven  to    seven       by   x    ;      call meat;      end;
do j=      555  to      550 - y             ;      call meat;      end;

do j=     1927  to     1939                 ;      call meat;      end;
do j=        x  to        y       by   z    ;      call meat;      end;

## Ring

Translation of: Phix

<lang ring> prod = 1 total = 0 x = 5 y = -5 z = -2 one = 1 three = 3 seven = 7

loopset = [[-three,pow(3,3),three],

```          [-seven,seven,x],
[555,550 - y,1],
[22,-28,-three],
[1927,1939,1],
[x,y,z],
[pow(11,x),pow(11,x) + one,1]]

```

for i=1 to len(loopset)

```   f = loopset[i][1]
t = loopset[i][2]
s = loopset[i][3]
for j=f to t step s
total += fabs(j)
if fabs(prod)<pow(2,27) and j!=0
prod *= j
ok

## Ruby

Uses chaining of enumerables, which was introduced with Ruby 2.6 <lang Ruby>x, y, z, one, three, seven = 5, -5, -2, 1, 3, 7

enums = (-three).step(3**3, three) +

```       (-seven).step(seven, x) +
555     .step(550-y, -1) +
22      .step(-28, -three) +
(1927..1939) +                # just toying, 1927.step(1939) is fine too
x       .step(y, z) +
(11**x) .step(11**x + one)
```
1. enums is an enumerator, consisting of a bunch of chained enumerators,
2. none of which has actually produced a value.

puts "Sum of absolute numbers: #{enums.sum(&:abs)}" prod = enums.inject(1){|prod, j| ((prod.abs < 2**27) && j!=0) ? prod*j : prod} puts "Product (but not really): #{prod}" </lang>

Output:
```Sum of absolute numbers:  348173
Product (but not really): -793618560
```

## Smalltalk

Ranges (called Interval in Smalltalk) are collections, which - like all collections - can be concatenated with the , (comma) message. Intervals are created by sending a to: or to:by: message to a magnitude-like thingy (i.e. other than numbers are possible): <lang smalltalk>prod := 1. sum := 0. x := 5. y := -5. z := -2. one := 1. three := 3. seven := 7.

(three negated to: 3**3 by: three ) , (seven negated to: seven by: x ) , (555 to: 550-y ) , (22 to: -28 by: three negated) , (1927 to: 1939 ) , (x to: y by:z ) , (11**x to: 11**x + one )

```   do:[:j |
sum := sum + j abs.
((prod abs < (2**27)) and:[ j ~= 0 ]) ifTrue:[
prod := prod*j
].
].
```

Transcript show:' sum = '; showCR:sum. Transcript show:'prod = '; showCR:prod</lang> The above creates a temporary "collection of ranges" and enumerates that, which might be inconvenient, if the collections are huge.
One alternative is to loop over each individually.

Of course, we definitely don't want to retype the loop body and we usually don't want to the code to be non-local (i.e. define another method for it).
That's what blocks (aka lambdas or anonymous functions) are perfect for: <lang smalltalk>prod := 1. sum := 0. x := 5. y := -5. z := -2. one := 1. three := 3. seven := 7.

action :=

```   [:j |
sum := sum + j abs.
((prod abs < (2**27)) and:[ j ~= 0 ]) ifTrue:[
prod := prod*j
].
].
```

(three negated to: 3**3 by: three ) do:action. (seven negated to: seven by: x ) do:action. (555 to: 550-y ) do:action. (22 to: -28 by: three negated) do:action. (1927 to: 1939 ) do:action. (x to: y by:z ) do:action. (11**x to: 11**x + one ) do:action. Transcript show:' sum = '; showCR:sum. Transcript show:'prod = '; showCR:prod</lang>

As another alternative to the first solution above, we can loop over the ranges. This avoids the concatenations and generation of the intermediate big collection (which does not really make a difference here, but would, if each collection consisted of millions of objects):

Works with: Smalltalk/X

<lang smalltalk>...

{

```   (three negated to: 3**3  by: three       ) .
(seven negated to: seven by: x           ) .
(555           to: 550-y                 ) .
(22            to: -28  by: three negated) .
(1927          to: 1939                  ) .
(x             to: y    by:z             ) .
(11**x         to: 11**x + one           ) .
```

} do:[:eachRange |

```   eachRange
select:[:j | ((prod abs < (2**27)) and:[ j ~= 0 ]) ]
thenDo:[:j | prod := prod*j ].
]
```

]. ...</lang> Notice: this creates only 8 objects and also demonstrates an alternative element selection scheme, which may be more readable.

Output:
```  sum = 348173
prod = -793618560```

Note) Dialects with no **-method should use raisedTo:, or else define an alias for it in Number as: <lang smalltalk>** arg

```   ^ self raisedTo: arg</lang>
```

For i = start To [stop] Step [step]
Yield i
Next
End Function
```

End Module</lang>

and Enumerable.Concat (along with extension method syntax) to splice the ranges, the program ends up looking like this:

<lang vbnet>Imports System.Globalization

Partial Module Program

```   Sub Main()
' All variables are inferred to be of type Integer.
Dim prod = 1,
sum = 0,
x = +5,
y = -5,
z = -2,
one = 1,
three = 3,
seven = 7
```
```       ' The exponent operator compiles to a call to Math.Pow, which returns Double, and so must be converted back to Integer.
For Each j In Range(-three,       CInt(3 ^ 3),        3     ).
Concat(Range(-seven,       +seven,             x     )).
Concat(Range(555,          550 - y                   )).
Concat(Range(22,           -28,                -three)).
Concat(Range(1927,         1939                      )).
Concat(Range(x,            y,                  z     )).
Concat(Range(CInt(11 ^ x), CInt(11 ^ x) + one        ))
```
```           sum = sum + Math.Abs(j)
If Math.Abs(prod) < 2 ^ 27 AndAlso j <> 0 Then prod = prod * j
Next
```
```       ' The invariant format info by default has two decimal places.
Dim format As New NumberFormatInfo() With {
.NumberDecimalDigits = 0
}
```
```       Console.WriteLine(String.Format(format, " sum= {0:N}", sum))
Console.WriteLine(String.Format(format, "prod= {0:N}", prod))
End Sub
```

End Module</lang>

To improve the program's appearance, a ConcatRange method can be defined to combine the two method calls, <lang vbnet> <Runtime.CompilerServices.Extension>

```   Function ConcatRange(source As IEnumerable(Of Integer), start As Integer, [stop] As Integer, Optional [step] As Integer = 1) As IEnumerable(Of Integer)
Return source.Concat(Range(start, [stop], [step]))
End Function</lang>
```

which results in a loop that looks like this: <lang vbnet> For Each j In Range(-three, CInt(3 ^ 3), 3 ).

```               ConcatRange(-seven,       +seven,             x     ).
ConcatRange(555,          550 - y                   ).
ConcatRange(22,           -28,                -three).
ConcatRange(1927,         1939                      ).
ConcatRange(x, y,         z                         ).
ConcatRange(CInt(11 ^ x), CInt(11 ^ x) + one        )
Next</lang>
```

An alternative to avoid the repeated method calls would be to make a Range function that accepts multiple ranges, in this case as a parameter array of tuples. <lang vbnet> Function Range(ParamArray ranges() As (start As Integer, [stop] As Integer, [step] As Integer)) As IEnumerable(Of Integer)

```       ' Note: SelectMany is equivalent to bind, flatMap, etc.
Return ranges.SelectMany(Function(r) Range(r.start, r.stop, r.step))
End Function</lang>
```

resulting in: <lang vbnet> For Each j In Range((-three, CInt(3 ^ 3), 3 ),

```                           (-seven,       +seven,             x        ),
(555,          550 - y,            1        ),
(22,           -28,                -three   ),
(1927,         1939,               1        ),
(x,            y,                  z        ),
(CInt(11 ^ x), CInt(11 ^ x) + one, 1        ))
Next</lang>
```

Note, however, that the inability to have a heterogenous array means that specifying the step is now mandatory. Using a parameter array of arrays is slightly less clear but results in the tersest loop. <lang vbnet> Function Range(ParamArray ranges As Integer()()) As IEnumerable(Of Integer)

```       Return ranges.SelectMany(Function(r) Range(r(0), r(1), If(r.Length < 3, 1, r(2))))
End Function</lang>
```

<lang vbnet> For Each j In Range({-three, CInt(3 ^ 3), 3 },

```                           {-seven,       +seven,             x        },
{555,          550 - y                      },
{22,           -28,                -three   },
{1927,         1939                         },
{x,            y,                  z        },
{CInt(11 ^ x), CInt(11 ^ x) + one           })
Next</lang>
```
Output (for all variations):
``` sum= 348,173
prod= -793,618,560```
