I am new to perl and am trying to write a script that will allow me to examine 7 different ranges (to be specific, 7 sets of concurrent numbers) and see if any of them have any values in common.
ie. A script that can be presented with 7 ranges of numbers and be able to say "ranges 2 and 4, ranges 5, 1 and 6, ranges 1 and 2 ...etc have numbers in common"
