Getting Weird RE (AtCoder Online Judge)

Revision en4, by vok8, 2020-05-25 17:34:13

  • Problem: XXOR

  • Submission-1: Link (Runtime Error)

  • Submission-2: Link (Accepted)

  • The difference between both the submissions is just the two cout<<""; statements, in the two "n" range for loops.

  • The cout<<""; statements are uncommented in Submission-2 and commented in Submission-1. And guess what, these statements convert a RE Submission to an AC Submission.

  • The code in Submission-1, for a Valid Random Input, runs finely in Codeforces' Custom Test, whereas it gives RE in AtCoder's Custom Invocation. (You may try, for more clarification and to find the reason!)

  • I found it weird! I am totally clueless about why this is happening. Can anyone please justify or explain, why is this happening?

  • Thank you!
