Hi,

To solve the issues of submitting the answers, you can mail them to gurus [dot] comments [at] gmail [dot] com

The steps to be noted are

1. Subject should be the Title of the Post (noting extra, nothing lesser)

2. You can submit your solution as many time as you want, just put a comment about which one you want to be considered.

3. Feel free to ask anything in the comments, any doubts etc, but mail the solutions.

4. For programming contests the same procedure can be followed or you can look for a link like this http://snippets.dzone.com/posts/show/4226 for the solution.

I hope this works as intended.

Peace!
