Wrong answer.
By basket_full, history, 2 months ago, In English

When I copy someone else's code and then submit the code it says "Wrong answer". But the same code says "Accepted" on the other's submission. Why does it happens?

How somebody supposed to help without something more concrete? Something obvious reasons:

  1. Mistake in copy-paste (I don't know how but I think it's possible)
  2. Mistake in problem (AC code solves different problem — maybe confusing with Div1/Div2 literas)
  3. UB in code then accepted code' author was just lucky.
  4. Since no one submission has been showed maybe it all was just hypotetical question.

This question is too generic to provide an accurate answer. Some possible reasons include Undefined Behaviour and randomizations in the algorithm you copied.
