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.

Hints/Tips Finding adjacent words | Comment 8 of 11 |
One useful footnote that we discovered setting this problem was that it is considerably faster to generate the 25N 'adjacent' words (for an N-letter word) and then eliminate all the non-words in this list than it was to search the N-letter word list for words with a single letter difference.
