CF Wrong Judgement on #483(div 2) Problem B.Minesweeper
On Codeforces Round #483 (Div. 2) [Thanks, Botan Investments and Victor Shaburov!] I got wrong answer in testcase#13 on Problem B. I literary stopped sleeping to figure out what went wrong, but as full testcase is not shown, I couldn't get any clue.
but, when I again submitted the same code today, It was accepted.
MikeMirzayanov please look into the system what caused the malfunction.
If possible anyone please explain why this happened.
