Slow and smooth September LunchTime 2015

2 min read

Registration – a word that everyone loathes, but cannot circumvent or miss it. This is why every registration date is of so much significance. And by the time we arrived at the September LunchTime 2015, we had the registration dates for both, IOI as well as ACM ICPC 2016. Now, we know you all are smart enough to not miss out on any of those dates, so without worrying about constantly reminding you about the last dates, we focused on getting you ready for the contests. And the only way we know to do that is by serving you the contests of highest order. So, we started getting the September LucnhTime 2015 ready for you all.

The responsibility for the early Sunday party went to the LunchTime veteran Sergey Kulik, who doubled as the problem setter and Russian translator for the contest. Following up on his footsteps we had Yanpei Liu, doubling as Mandarin translator and problem tester for the contest. And the Vietnamese translations came from Team VNOI. The editorials for the problems came from Pawel Kacprzak, while Praveen Dhinwa and Pushkar Mishra donned the admin hat and Rahul Arora proof read the problem statements. With IOI registrations opening few days from the LTIME28 it just the right time for all the school students to get their preparations going.

The seasoned problem setting panel used their experience to treat the participants with a problem set that not only will test them, but will also help them evolve as a competitive programmer. And that’s exactly what they need ahead of a busy programming season ahead. And the participants received the problems with the same love and zeal. We started getting submissions right from the very first minute of the contest with SPALNUM getting the first submission of the contest. It also was the first AC for LTIME28. After the first submission in the first minute we started getting submissions almost every minute, with the number of submissions per minute fluctuating on both sides of scale.

There was not much happening on the rank tables in terms of changes in name occupying the top slots. However, the competition between our LunchTime pros yutaka1999, fleimgruber, meteora, rajat1603, kmcode, and additya1998 was constantly heating up. And it was only a matter of time before someone cracking an extra subtask or a complete problem to take advantage over the others. So, who was it going to be this time? We were in the final stages of the contest and we still did not have a clear name to paste on the top of rank table. However, after two unsuccessful attempts yutaka1999 cracked PATTMATC and took the lead over others. And it didn’t take him too long to seal the contest in his favor as he solved MANYLIST with his first submission on it. We still had one hour left into the contest, so we were not drawing any conclusions till it was over. And now that it is long over, let us not keep you waiting to meet the winners of September LunchTime 2015.

We start with ROW top 10:

A big round of applause for all the young champs!

It’s editorials time. We hope you have already used them to good effect to strengthen your practice for the impending ZIO and ZCO. But if you have not, you can still do a lot with them. So, let us take you to them.

That brings us to the last segment of the post. Even though, it is a long delayed post, we hope we have succeeded in bringing in the real essence of the September LunchTime through it. However, if you have any reservations regarding the contest or the post, kindly do let us know. You can reach us at: feedback@codechef.com

That will be all for now.

See you all at the contests.
