April 2011 Challenge Winners!

1 min read

Hi CodeCheffers,

The April Challenge 2011 is over!

The contest went through a few hick-ups this month, we faced downtime of our judge SPOJ for about 10 hours, due to some construction work which caused a network breakdown in Poland, thats where our judge is located. We therefore extended the contest by 24hours to make sure no one lost out during this downtime. We also had a few changes in our test cases during the contest and had to re-judge the problems L2GRAPH and RECTCNT.

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 and Snigdha Chandan were the problem setters while  Rajiv Kumar was the diligent tester of this month’s contest.

Lets look at some Statistics and then move on to see the final winners list.
