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))
Java
<java>Collection<Type> collect; ... for(Type i:collect){
System.out.println(i);
}</java>
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>
