Loops/Foreach
< Loops
You are encouraged to solve this task according to the task description, using any language you may know.
Loop through and print each element in a collection in order. Use your language's "for each" loop if it has one, otherwise iterate through the collection in order with some other loop.
Common Lisp
(loop for i in list do (print i))
Forth
create a 3 , 2 , 1 , : .array ( a len -- ) cells bounds do i @ . cell +loop ; \ 3 2 1
Haskell
forM_ collect print
Java
<java>Collection<Type> collect; ... for(Type i:collect){
System.out.println(i);
}</java> This works for any array type as well as any type that implements the Iterable interface (including all Collections).
JavaScript
This works for any object, as well as arrays.
for (var a in o) print(o[a]);
Logo
foreach [red green blue] [print ?]
OCaml
List: <ocaml>List.iter
(fun i -> Printf.printf "%d\n" i) collect_list</ocaml>
Array: <ocaml>Array.iter
(fun i -> Printf.printf "%d\n" i) collect_array</ocaml>
Perl
<perl>foreach $i (@collect) {
print "$i\n";
}</perl> The keyword for can be used instead of foreach. If a variable ($i) is not given, then $_ is used.
PHP
<php>foreach ($collect as $i) {
echo "$i\n";
}</php>
Python
<python>for i in collect:
print i</python>
