In case you missed it: A recap of our 100th Cook-Off

2 min read

The November Cook-Off may be behind us, but the excitement still hasn’t left our system! This was CodeChef’s landmark 100th Cook-Off and we rewarded not only our top performers but also a bunch of participants, selected randomly, to show our gratitude. Keep reading to know what went down during this historic Cook-Off.

Over in Div 1, Japan’s number 1 competitive programmer uwi, stole the show by securing the first rank while the second spot went to India’s own rahuldugar. During this Cook-Off IITian rahuldugar increased his rating to 2484, he only needs a few more rating points to join the exclusive 7-star club. We’re rooting for you, Rahul! uwi, meanwhile, has enjoyed top billing in Japan (national rank 1) and a global rank of 8 for a while and only needs around 70 rating points to steal ACRush’s spot in the global top 5. We’ll be waiting to see if he takes up the challenge. (UPDATE: We may have inadvertently predicted a huge rank shift for uwi! Wait for our Lunchtime recap to know more!)

Also in Div 1, artistmusicant and ll931110 who were at ranks 3 and 4 respectively, both graduated to 5 stars during this Cook-Off. artistmusicant was notably the only female programmer in the top 10 during this Cook-Off so hope she inspires all the girl-coders out there!

grikukan from Russia stirred things up in Div 2 where he earned the first rank. This University student is teetering on the brink of Div 1 with a rating of 1786, but he’s had a tumultuous journey through CodeChef’s contests slipping from 6 stars to 3 stars last year, and nobody knows better than us that anything can happen in a CodeChef contest! petergendy4 from the US swooped into second place with a score of 2, and in the process went from 3 stars to 4.

Among school-level coders, sanroylozan from Hungary, evpipis from Greece and adhyyan1252 from India were a cut above the rest. These school students are all 6-star coders, we hope they can all graduate to 7 stars soon and give the more experienced coders some competition.

There were no seismic shifts in this month’s Div 1 and Div 2 order, but 61 users from Div 2 graduated to Div 1 while over double that number (137) fell back to Div 2 from Div 1. Just a reminder that in the word of competitive programming, you can’t get too comfortable with your rating! You have to keep practising and competing to stay on top.

As far as participation goes, India had the most participants with over 2000 coders taking part in the Cook-Off. The United States and Bangladesh were tied in second place with 23 participants each while 9 Cook-Off coders were from Russia.

The problem Truth and Dare, emerged as the most solved problem with 1781 successful submissions out of a total of 4355 while Data Pipelines was the least solved with 0 successful submissions in Div 2. In Div 1 Elephants in a Pond got just 1 successful submission. You can check out editorials for all the Cook-Off problems here.
