Winners for September 2011 Challenge!

1 min read

Greetings CodeCheffers,

The Challenge for September 2011 has concluded, and once again, there was no exclusive winner on the Indian side of things. On the global side, however, we saw a clean victory, of which we shall inform you in just a few lines. 🙂

Before moving on though, I’d like to mention that this month’s participation very nearly equalled the highest ever participation for a long contest; I am sincerely pleased to see so many people constructively using their free time. 🙂

Another unusual highlight was the single successful submission for the challenge problem TILT… what happened guys? The problem setter himself was surprised.

A massive under-10 tie saw the 9th rank cover nearly 140 people! Talk about neck-and-neck…

Now, for the honorary problem setters and tester, whom all of us here are deeply ingratiated to:

David Stolp, Gennady Korotkevitch, Saransh Bansal, Imran Sunny and Vamsi Kavala prepared the problems while  Shilp Gupta sampled them before they were served to you.

Let’s look at some Statistics and then move on to see the final winners list.

Length of Contest Unique Participants Total Number of Submissions User who have solved at least one problem
