When you do a for loop :
for (@array)
{
s/1//g;
}
the implicit $_ in the loop becomes an alias for the real element - so by
modifying the element in the loop you're actually modifying the "real" one
in the array.

PS you could use map here as well, but it's in a void context - big no-no
:-) I personally liked the s/// for @array expression.
