Word Ladders (Posted on 2003-09-24) Difficulty: 4 of 5
Write an algorithm to solve word ladders such as Word Meld 1 or Word Meld 2. Input consists of the starting and ending words and the maximum number of steps allowed. Available are files containing lists of words of any given length; call one such file, say WORDS5.TXT containing a list of words of 5 letters each, and so on.

File I/O looks necessary. This most likely would benefit from recursion.
