RE: Answer: How do I find the Nth occurrence of a pattern?

[eak]

I have to correct my code. I passed in a reference and never used it :(.

#!/usr/bin/perl -w
my @string = (34, 56, 78, 90, 98, 76, 54, 32, 10, 12, 13, 16, 19, 20, 
+10, 56);
 
sub nth_iter{
    my ($item, $n, $list) = @_;
    ( map { $list->[$_] == $item ? $_ : (); } 0..$#$list )[--$n] or -1
+;
}
 
print nth_iter(78, 1, \@string);
