Hello All, I was trying to do an old problem https://codeforces.com/contest/604/problem/A where I got the wrong answer for a testcase while submitting the solution and I ran the same testcase on few other compilers, I got the correct answer. Here are the screenshots from the results from codeforces, codechef, ideone, geeksforgeeks for the solution https://codeforces.com/contest/604/submission/93113404 . Please help if anyone knows the reason.
