Hello Monks!
So, it seems like a very trivial problem for me, but my code so far is not working properly.
What I want to do is, supposedly you have two numerical ranges, like:
117-137    AND 112-130

and you want to check whether the second one has an overlap of at least 5 positions with the first one (at least 5 positions must be included in the first one).
How do you proceed? I tried:
$flag_correct=0;
if( ($second_beg>=($first_beg-5)) && ($first_beg<=($second_beg+5)) && 
+($first_end>=($second_end-5)) && ($first_end<=($second_end+5)) ) {$fl
+ag_correct = 1;}

but this doesn't work correctly, because in the case mentioned above the flag remains 0.
