Re: word matrix

Thanks much for your time on this - I'm going to give this code a try - much appreciated :) Best, Mike D On Mar 28, 2006, at 12:53 PM, Shaunak Kashyap wrote:

Here is my first cut at the problem. It is probably not the most optimal solution in terms of algorithmic complexity and it could also do without the use of global vars and such, but it should give you some ideas.

Could you post a sample of what you have and what you want to end up with? It'll be easier for us to work out rather than guess at what
