1 min read

Hi CodeCheffers,

The May Challenge 2011 is over!

This month we saw a good distribution of difficulty levels across the problems, similar to last month the overall participation has been consistently increasing :). We also saw some intense battle for the top spot between the top 10 global winners, eventually Liang Yaxiong from China bagged the top rank in his very first contest at CodeChef. Congratulating him and all the other winners for their participation.

Before we move on to the next section of the blog post, a special mention of the people who made this contest possible:

Zac Friggstad, AnhDQ, Anton Lunyov and Snigdha Chandan were the problem setters while  David Stolp was the diligent tester of this month’s contest.
