This last contest of October was certainly a fitting way to say goodbye to the month. With some stunning competition from the red coders and equally challenging problems, this was how all the action went down.
The Pleasant Problems
For this contest, both the divisions were assigned 5 problems each. The participants were quick to act and we had our first submission within two minutes as Gennady solved the problem Chef Likes Good Sequences. At the end of the competition, this problem turned out to be the crowd-favorite for Division One as more than 440 players solved it. Another popular problem in Division One was Cute Chef Gift. Gennady was once more the first person to solve the problem and by the end of the contest, this problem had garnered a total of 355 successful submissions. On the other hand of the spectrum, Division One saw its fair share of difficult problems. Counting Spaghetti seemed to have all the players in for a loop as only 44 out of 1050 who sent in submissions walked home with the green-tick. Another problem that turned out to be an absolute nightmare for the players was Chef and Edge Flipping. Only two players were able to solve the problem despite a ton of 7-star coders attempting it. As a treat for you, Bulgarian coder Radoslav Dimitrov will be explaining this problem in an in-depth tutorial. You can tune in to watch it here, tonight at 9.
We got in touch with solo problem setter for this contest Mohammed Ehab to ask him whether the performance on his problems was expected.
“Mostly yeah, although I’m surprised with and kinda proud of EFLIP. So many (literally) legendary participants yet only 2 solved it. I was expecting more full scores.”
Mohammed’s problem certainly gave all the top players a run for their money, and we hope we get to see more such participant vs problem setter action in the future.
Meanwhile, Division Two had its own party raging. The problem that acted as the band-wagon here was AND Plus OR. Around 11250 players sent in answers for the said problem and over 5250 walked home with the green-tick. Problem “Chef Likes Good Sequences” was also showered with its fair share of love as it saw around 550 successful submissions. Talking tough problems for this division we had Chef Is Just Throwing Random Words. By the end of the contest, only 246 players had cracked the code for this problem. Another challenging problem for this division was Cute Chef Gift which was solved successfully by only 97 players.
