I have been trying to solve the problem Nudist Beach, here at http://codeforces.me/contest/553/problem/D. However, I find that when I submit I get a different output as that from ideone, or my local compiler. Even more strangely I get different results depending on whether I submit the file, or whether I copy-paste the code into the editor.
When I submit by file, I get a response of WA on the first testcase. When I submit by copy-paste, I get time limit exceeded. When I run the same code in ideone, or my local compiler, for the first testcase, I get the correct output instantaneously.
Please find attached the following code-links. Ideone link. http://ideone.com/INKqhS. WA submission link. http://codeforces.me/contest/553/submission/19136417 TLE submission link. http://codeforces.me/contest/553/submission/19136401
Is this an error in the compiler/judge, or is it at my end? Thanks for taking a look at this.
