Hi - A general computer science question- Given the levenshtein distance between two strings and one of the strings S1, is it possible to re-create the second string. For example - S1 = "RUBY" S2 = "BRUY" lev_distance = 3 Given 3 and S2, is it possible to recreate S1?? Many thanks, -- Posted via http://www.ruby-forum.com/.
