Hello everyone! I got a WA on test case 59 in the second question of Manthan 2k16 633B — A Trivial Problem in the system testing phase of Codeforces . But when I checked the judgement protocol after the contest , I found that my answer for test case 59 was displayed incorrectly . Actually the correct answer for test case 59 was 0 and I was getting the same correct answer on ideone.com (link — Click Here To See Ideone Solution, but there was a different answer given by the judgement protocol for this test case because of which I got a WA which should have been correct. I have also provided a screenshot of the judgement protocol for this question(submission no. 16359094) (link — Submission Page. This problem is not only with me , many of my friends have faced the same problem . Therefore, the authors of this contest are requested to look into this issue.
