Currently I was practicing oin a virtual contest and for this problem https://codeforces.net/contest/1003/problem/C↵
I got wrong answer for test case 1 ( though everything was working correctly offline and on other online compilers for same test case) after the contest when I looked at the test case and changed the header file to iostream, the same solution got Accepted. Can anyone please help me to figure out why such error occurred.↵
