https://mirror.codeforces.com/contest/359/submission/227495328 The question id is: https://mirror.codeforces.com/contest/359/problem/D Here I have used a simple binary search which is overall giving time complexity (o(n)logn) there is sieve technique used in code which can compute in O(nlog log n) time so overall the entire code wont take more than O(nlogn) as per me . Please Correct me if there is some mistake.
