Jumble Word Solver

Posted on May 28, 2009 by

A jumble word solver. Finds all meaningful words that can be made my rearranging the characters of a certain string. Two methods have been described. One searches sequentially through a list of words, another searches through a tree where the words are indexed. The tree method is very fast and only needs maximum of “n” iterations to search all the matching words, where “n” is the length of the input string. Continue reading →
