Have I done something wrong or Codeforces's C++ online judge is wrong?
By satinja, history, 9 years ago, In English

Hi everyone, I have recently participated in codeforces round #308 div2. My submission for problem got wrong answer on pretest 5th. After contest I checked output for same code on ideone (Ideone link here) and my local machine then got correct answer. I don't know why online judge of codeforces was showing wrong output. I request all of you to check on your local machine and let me know if my code is giving any error.

Probably because of pre-built pow function. Although I don't know why's it so.

      Pow function gets warning on my version of gcc. So I'd rather code one myself. There it is.

      UPD: WA5 on CF. Seems the trouble is caused with the solution itself. Sorry for the wrong idea.
