It's offical, another winner!
Just to recap, here is our latest challenge:
Using ASP.NET, C#, and LINQ to Objects create a web page with a form that accepts a comma delimited list of integers and outputs them into their word representation followed by a line break, with an option to sort by word, integer, or original order. Also, there needs to be an option to output 10, 20, 30, or All values.
We received a lot of good solutions but one man has seperated himself from the pack. That guys name is Nate S. from Greenville, IN. Nate's solution hits all the high points of the requirement and outputs a very clean reponse to the user. Great job Nate! Your gift certificate should be in your inbox within the hour.
We truly appreciate all of our participants for taking part and stay tuned for our September challenge!
Nate's winning solution!
