# N'th

**N'th**

You are encouraged to solve this task according to the task description, using any language you may know.

Write a function/method/subroutine/... that when given an integer greater than or equal to zero returns a string of the number followed by an apostrophe then the ordinal suffix.

- Example

Returns would include `1'st 2'nd 3'rd 11'th 111'th 1001'st 1012'th`

- Task

Use your routine to show here the output for *at least* the following (inclusive) ranges of integer inputs:
`0..25, 250..265, 1000..1025`

**Note:** apostrophes are now *optional* to allow correct apostrophe-less English.

## 11l

```
V _suffix = [‘th’, ‘st’, ‘nd’, ‘rd’, ‘th’, ‘th’, ‘th’, ‘th’, ‘th’, ‘th’]
F nth(n)
R ‘#.'#.’.format(n, I n % 100 <= 10 | n % 100 > 20 {:_suffix[n % 10]} E ‘th’)
L(j) (0..1000).step(250)
print_elements(Array(j.+25).map(i -> nth(i)))
```

- Output:

0'th 1'st 2'nd 3'rd 4'th 5'th 6'th 7'th 8'th 9'th 10'th 11'th 12'th 13'th 14'th 15'th 16'th 17'th 18'th 19'th 20'th 21'st 22'nd 23'rd 24'th 250'th 251'st 252'nd 253'rd 254'th 255'th 256'th 257'th 258'th 259'th 260'th 261'st 262'nd 263'rd 264'th 265'th 266'th 267'th 268'th 269'th 270'th 271'st 272'nd 273'rd 274'th 500'th 501'st 502'nd 503'rd 504'th 505'th 506'th 507'th 508'th 509'th 510'th 511'th 512'th 513'th 514'th 515'th 516'th 517'th 518'th 519'th 520'th 521'st 522'nd 523'rd 524'th 750'th 751'st 752'nd 753'rd 754'th 755'th 756'th 757'th 758'th 759'th 760'th 761'st 762'nd 763'rd 764'th 765'th 766'th 767'th 768'th 769'th 770'th 771'st 772'nd 773'rd 774'th 1000'th 1001'st 1002'nd 1003'rd 1004'th 1005'th 1006'th 1007'th 1008'th 1009'th 1010'th 1011'th 1012'th 1013'th 1014'th 1015'th 1016'th 1017'th 1018'th 1019'th 1020'th 1021'st 1022'nd 1023'rd 1024'th

### Run BASIC

The Liberty BASIC solution works without any changes.

### Sinclair ZX81 BASIC

Works flawlessly with 2k or more of RAM. With 1k, the subroutine itself works but you can't quite print all the tests: the program crashes with an 'out of memory' error code after 1017th. (A slightly less useful and readable version gets as far as 1023rd; 1025th is probably attainable, but might involve obfuscating the program more than is appropriate for this site.)

Alternatively you can use the builtin ord(), and a more functional style, as follows (same output)

function do_one(integer n, string apostrophe) return pad_head(sprintf("%d%s%s",{n,apostrophe,ord(n)}),7) end function procedure do_set(sequence s, bool bApostrophe=false) puts(1,join_by(apply(true,do_one,{s,{repeat('`',bApostrophe)}}),1,10,"")&"\n") end procedure constant {rs,re} = columnize({{0,25},{250,265},{1000,1025}}) papply(true,do_set,{apply(true,tagset,{re,rs}),{false,true,false}})

## PHP

```
function nth($num) {
$os = "th";
if ($num % 100 <= 10 or $num % 100 > 20) {

## Picat

`nth/3`

is a built-in predicate in Picat, so let's call the functions `nth2/1`

and onward.

### Prolog style

```
nth2(N) = N.to_string() ++ Th =>
( tween(N) -> Th = "th"
; 1 = N mod 10 -> Th = "st"
; 2 = N mod 10 -> Th = "nd"
; 3 = N mod 10 -> Th = "rd"
; Th = "th" ).
tween(N) => Tween = N mod 100, between(11, 13, Tween).
```

### Function with explicit conditions

```
nth3(N) = cc(N,"th"), tween(N) => true.
nth3(N) = cc(N,"st"), N mod 10 = 1 => true.
nth3(N) = cc(N,"nd"), N mod 10 = 2 => true.
nth3(N) = cc(N,"rd"), N mod 10 = 3 => true.
nth3(N) = cc(N,"th") => true.
% helper function
cc(N,Th) = N.to_string() ++ Th.
```

### List of suffixes

```
nth4(N) = Nth =>
Suffix = ["th","st","nd","rd","th","th","th","th","th","th"],
Nth = N.to_string() ++ cond((N mod 100 <= 10; N mod 100 > 20), Suffix[1 + N mod 10], "th").
```

### Test

```
go =>
Ranges = [ 0..25, 250..265, 1000..1025],
foreach(Range in Ranges) println([nth2(I) : I in Range])
end,
nl.
