Here is the splice version. Make sure you understand what's going on before you submit to whomever... (there is a twist...)

#!/usr/bin/perl use strict; use warnings; my @first = qw(Can unlock secret); my @second = qw(you the code?); my @mixed = interleave_words( scalar(@first), @first, @second ); print "Result: @mixed\n"; sub interleave_words { my $count = shift; my @results = splice @_, $count; foreach my $index ( 0 .. $count-1 ) { splice @results, 2*$index, 0, shift; } return @results; }
