dear coordinators, come to your senses and do not fill the Division 2 tasks with pure mathematics and implementing stuff, there are a bunch of other things to learn... and please, do not coordinate a round in which C2 has less solves than D Just for god's sake, contests are not implementation and number theory trainings

SFME I thinks it's time the schedule of CF rounds be more organized, there have been 14 days in which there hadn't been any contest and weeks there had been 3 contests in a row. I am aware that there might be difficulties for problem setting and the times should be flexible, but there are other platforms having this flexibility but also having a weekly routine. It's a pity a nice platform like Codeforces with all its capabilities has little discipline.

A couple of months ago, I posted this: https://codeforces.me/blog/entry/127693 And got no response Who should I tell about this problem?

I submitted this recently and found out the algorithm is incorrect, but surprisingly, it got accepted! https://codeforces.me/contest/22/submission/253924838 This submission won't work for the following test: 5 7 11100000 11100000 00000000 00000000 11100000 11100000

Hello guys I am stuck in solving the problem of "E-singer's tour". I am solving it using O(n) but I have no idea why it gets me a TLE error. Even though getting the input is O(n) and my code is O(n). I have no idea how to solve this problem. I even don't find any other way. my submission: https://codeforces.me/contest/1618/submission/249522519 my other submission that might have more optimization:https://codeforces.me/contest/1618/submission/249523839

Hello code forces, this is my first blog entry as a newbie and I hope it'll be answered (I don't become surprised if nobody answers me! the problem I have is a misjudging happening in my code's judging. I noticed while reading the first test cases that my code returns something else that what is written there as "output", I mean when I give the very same test to console it returns the right answer nevertheless it shows my code outputs something else. if needed https://codeforces.me/contest/1894/submission/237543088 Sub no.237543088 who should I go to?
