Hello, There is an error in the constraints of Y in the problem statement of https://www.codechef.com/problems/B3 I believe it should be 2100000000 ≤ Y ≤ 2100000000. Also Y=0 does not appear in the tests. Thus, the constraint could be rewritten as 0 < Y ≤ 2100000000. Thanks! asked 12 Dec '17, 08:54
