hi guys!

I have two array and I want to compare the arrays as follows:
# if I have:
my @arr1 = qw(2 4 5);
my @arr2 = ('1,nfs', '2,afp', '3,cifs', '4,dns', '5,backup');

[download]
I want to stay with stay with the entries in @arr2 that their prefix is the digits from @arr1:
# therefore from the above arrays I want to get:
@arr3 = qw(afp dns backup);

[download]
what is the shortest way?
Thanks
