in thread assigning arrays as values to keys of hash

That sounds like a challenge :)

#!/usr/bin/perl # use strict; use warnings; use Data::Dumper; my %hash; $hash{ $& x /\S+/g }{ $& x //g } = 1 while <DATA>; $_ = [ keys %$_ ] for values %hash; print Dumper \%hash; __DATA__ snake fangs snake tail snake fangs bird feathers bird beak snake scales bird beak bird claw bird wings

(I just wanted to post code that, if the problem is a homework assignment, will force the teacher to make the student go to the front of the class and explain on the blackboard, in detail, to the rest of the students, how the solution works :)
