in reply to Re^4: Longest common substring with N mismatches
in thread Longest common substring with N mismatches

Hi ikegami! Many thanks! I forgot to post it here, I think I solved my problem with the String::Approx module (since I always had just 1 mismatch). But I will try your approach as well, it seems to be more solid anyway...
Many thanks again!

    Not quite. "Word" and "world" have one mismatch according to that module.
