ACM is no longer sponsoring ICPC and the competition name is no longer ACM-ICPC. Now it's become only ICPC. Though ACM-ICPC looks more cool ;).

Perhaps a lot of us don't know about this fact and still using ACM before ICPC ( so did in Codeforces Round #590 (Div. 3) ).

Why I am getting different output? Someone please explain the reason behind the WA. Ideoned code: https://ideone.com/ZjNybK CF Submission: https://codeforces.com/contest/1114/submission/49755099

Whenever I run my code on compiler it's showing output "-1", but Codeforces shows "1" and gives WA. Can anyone explain the reason behind this?
