Consider two strings: Hello, world! Yo, there. What is the "number of edits happened between the two versions"? It could be: * Zero. I just typed them both from scratch, no editing occurred between them. * Two. Two words are different. * Ten or so -- counting changed characters. * Three. Two words and a punctuation mark are different. In other words, your problem here is that you haven't actually described what you want. Slow down. Think! Describe what you want clearly enough that any other person who reads your description can always come up with the same answer you would for a given set of inputs. -s -- Copyright 2010, all wrongs reversed.
