comparing ranges of numbers between 2 files

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Hello everyone!
I have 2 text files with some number ranges, e.g.:

100000313-100001222
[download]

in one file and 100000391-100000947 in the other.
My goal is to take each line from each file and see if it is somehow "contained" in the other. As you can see from the example, the range 100000391-100000947 is within the range 100000313-100001222.
Can you provide me with some help as to how I can deal with such a problem?
Is there some module or something?
Thank you very much for your time!

See threads like finding intermediate range values from two file columns, Calculate the overlap length between two ranges, find the coverage of sequence in a particular range, Match Numeric Range, and Range overlap (with a lot of ranges). In particular, Set::IntSpan will probably do exactly what you want. Added two more links.	[reply]

Since you only need to see if it's contained it's simply checking `$a1 < $b1 and $a2 > $b2` for each combination of lines from file A and B. you can use `my ($a1, $a2) = split '-', $line` to `split` the ranges.
