Yay! The biggest Long Challenge Yet. Literally!

2 min read

September officially rang the bell for the ACM ICPC 2016 – 2017 season in India. In other parts of the world, though, the regionals were already happening and teams from different universities were moving forward towards the World Finals. In India, the registrations for the regionals had just started and the hunt for the perfect team member was on. Even the closest of friends were subjected to great scrutiny, on their programming skills and how well they can cope up with the pressure. How do we know that? Well, we’ve got informers…. Just kidding, we imagine that’s what must be going on in the hostels during the programming season; but whatever. So, while some were still hunting for the team members, few others had already registered their teams and were busy preparing for the regionals.

A cracking contest with some testing problems was something everyone was looking for. So, we obliged with our September Challenge 2016. There still were two more contests in Cook-Off and LunchTime to follow, but the Long challenge was a great start as it helps the participants solve problems and develop new concepts during the ten day course of the contest. And our problem setters had cooked some really interesting problem set revolving around Chef and his many escapades involving his friends, Spaghetti, Palindromes etc. Now, we are not an expert in problem solving, so we don’t know how much the problems helped you guys in your preparation, but we would like to know form you, how were the problems? Did they satisfy your programming buds? Were they fun to play around? So, do let us know your thoughts on the contest, the problems our problem setters would love to read them.

Now, let’s move towards the contest. The September Challenge 2016 started with 7 problems, as the remaining three needed a tad more sautéing. Or so we thought. The remaining three problems were added in the latter stages of the contest, which meant that for a good period of the contest there were only 7 problems. And to make it fair and to give everyone enough time with the newly added problems, the problem setting panel decided to extend the contest to three more days. While there we were questioned on that decision of ours, a majority of participants were pleased with it. At least that’s what the numbers from the contest suggest. Yes, they were huge. So, huge that they made September Challenge 2016 our biggest ever long challenge. Yay! And it’s only fair that we share those numbers with you, after all, you made them.

So, here they are for you:

  • Total Users: 10448
  • Total Submissions: 173111
  • Number of distinct users with correct submissions: 9057
  • Total users from India: 3256
  • Total users not from India: 7192

Now, the big numbers also mean that the competition on the rank table was fierce, with the likes of ceilks, anta0, alex_2oo8, the latest sensation alladdin and many others all going at full throttle towards the top. While the names atop of the table were catching everybody’s attention, there were few shockers as well. Contrary to popular believe the seasoned campaigners and the popular names like ACRush, anudeep2011, rns4, lebron and few others seemed having a bad day at the office. But that’s just the part of the game, we are sure they will come back strong and will give us many exciting contests in the future. For now, let us have a look at the rank table for September Challenge 2016 and congratulate al the winners on their performance.

As always, we start with the girls:

The ROW top 10:

The Indian Top 20:
