A thundering debut amid the biggies

3 min read

The June Challenge 2015 came on close heels with the third and final qualification round of our SnackDown 2015. Teams who qualified for the elimination round were sharpening their blades at every opportunity presented to them. The teams who were still fighting for a slot in the top 500 teams in the SnackDown elimination round, were just looking for any opportunity they can get their hands on. And it all reflected in the final statistics for the contest. The participants left no stone unturned to perfect their preparations. And the rest as they say is history. So, let’s have a look back at, what was a beautiful prologue to a blockbuster.

The star studded problem setting panel for June Challenge 2015 featured, Amit Pandey, Pavel Sheftelevich, Sergey Nagin, Shchetinin Kirill, Shiplu Hawlader, Vasia Antoniuk, and Vitalij Kozhukhivskij. Among them we had a debutant in Shchetinin Kirill. Give a big round of applause to our new problem setter. We hope you enjoyed ANCOIMP, his first problem on CodeChef. If you have any feedback on the problem do send it us at: feedback@codechef.com. The testing for the ten problems to make them testing for you, was done by the duo of Mahbubul Hasan and Sunny Aggarwal. The editorials to help you with your doubts and queries regarding the problems were penned by Balajiganapathi Senthilnathan, we hope you enjoyed them. And finally, the Mandarin and Russian flavors for the problems, as most of the contest, they came from Minako Kojima and Sergey Kulik respectively. We hope you enjoyed the translations. If you think you can add more flavors by providing translations in more languages, feel free to contact us at: problems@codechef.com.

Now, from the problem setters to the participants who were all geared up to try their hands on the problems. The submissions into the June Challenge 2015 started right from the word go. The first submission came inside the first five minutes from rivudas on CBARG. And immediate after that we had amitsaharana trying the same problem and meeting the same fate. Two wrong answers to start the contest with! That cannot be good sign? That’s what we also thought, however, by the contest ended, that exclamation of shock had turned into the exclamation of joy, as CBARG turned out to be the easiest problem from the contest. We all have off days. Don’t we?

After the slow and steady submission flow primarily on CBARG on the first day, the contest picked up some pace on the second day. We were joined by the big three ACRush, rns4, and mugurelionut. And, knowing the genius of those three, we pretty much knew how the top of the rank table will look at the end of the contest. However, even they did not have their first submissions accepted. Talk about “one-of-those-days.” And even though you want them have an ideal start; we were just going gaga over the brilliance of the problem setting panel. Although, we knew they will find their way to the top, but still we were all praises for our problem setters.

Now, while we were busy following the performances of the big three, we happen to overlook another debutant in our contest. But this time, as a participant. It was rns_kjch, who made over ten submissions, getting different errors, before getting his first submission accepted. And although it took some time for him to find his first AC, that did not deter him from trying his hand on different problems. As a matter of fact, he tried his hand on CBARG, CHPLGNS, STDYTAB, FRNDMTNG, and CHSTR inside the first hour of him joining the contest. We think he wasn’t told that the contest is of ten days. Or may be speed is his forte. And if that is the case, we would love to see him crack our Cook-Offs. Despite his quick submissions on more than half the problem set, rns_kjch kept going into the contest till the very last day. And his thundering debut changed the entire look of the final rank list. It wouldn’t be an exaggeration to say that it was one of the finest debuts we’ve seen in any of our contests. If you know of any other, do let us know.

To give you a glimpse of it, let us take you through the final rank tables, featuring all our victors from June Challenge 2015.

We start with the ROW top 10:

And, top 3 from India:

Let’s give it up for all the winners of our June Challenge 2015.

And now, the final stats for CodeChef June Challenge 2015:

  • Total Users: 6799
  • Total Submissions: 98482
  • Number of distinct users with correct submissions: 6304
  • Total users from India: 5444
  • Total users not from India: 1355

To have a debutant win a contest that had close to 7K participants is just a testimony to the potential of the debutant. It sends a clear message to his counterparts for the coming contests. And gives us one more reason to grab a big tub of popcorn and enjoy the fierce rivalry between the newbie and the established. We hope you too will enjoy it. Now, let us take you through the editorials of June Challenge 2015. We are sure you already would have gone through them, but if you have not you can enjoy them now:

With that, it’s time now to conclude this long June Challenge 2015 blog post. We hope you enjoyed it as much as you enjoyed the contest. So, do send us your thoughts on the contest, on the blog or on anything you would want to discuss with us at: feedback@codechef.com

We will come back soon, with the blog on June Cook-Off 2015.

Till next time, adios.

    You mean “they” instead of “he” because I am sure rns_kjch participated as a team(see the times in https://www.codechef.com/COOK59/status/ANKGAME,rns_kjch and https://www.codechef.com/COOK59/status/ANKNIM2,rns_kjch). This is a standard issue regarding North Korean participants – see http://codeforces.com/blog/entry/14150 and https://discuss.codechef.com/questions/45900/kgcstar-and-kutengine-competing-in-teams. The worse thing is that Codechef does not disallow this officially.
