The January Cook-Off has ended, and it was quite a contest. An unexpected number of participants, the highest we’ve ever had on CodeChef, caught us unaware and caused glitches for some participants. While we work to improve that, here’s a recap of the otherwise amazing competition.
A Powerful Problem Set!
The players had their work cut out for them, as all three Divisions were given six problems to solve. Problem Mex Subsequence was the most popular in Division One as it garnered over 120 accurate submissions by the end of the contest. Another problem that was showered with attention in Division One was Not Too Colourful. A solid 85 players cracked the code but the accuracy rate was only 28.21 percent. Talking tough problems for the Division, Partition Ways and Equal Gifts were definitely the coders’ worst nightmare. Partition Ways had only 7 successful submissions, while Equal Gifts accumulated merely 6 green ticks.
For Division Two, the problems that played crowd-favorite were Prime Tuples and Maximize Islands. While Prime Tuples had the more successful submissions at 1800+, Maximize Islands had the higher accuracy rate at 32.21 percent. Problem Prefix And seemed to have all the players in a fix as we saw only 6 correct answers. Equal Gifts was the villain once again as only 3 Division Two players walked home with a green tick.
Moving on, the problem that everyone enjoyed solving in Division Three was Password. While 4100+ players solved the problem the accuracy rate was rather low at 23.72 percent. Another problem that the players seemed to favor was Distinct Pair Sums, as the problem drew in 4000+ accurate answers. The boons of Division One turned out to be the bane of Division Three as problems Mex Subsequence and Not Too Colourful got only 15 and 8 successful submissions respectively. However, we know our budding programmers have a lot more to offer, and we are patiently waiting for the next contest to see them grow.
