CodeChefRating 2535Open on judge ↗

Problem Statement Chef has a undirected graph G. This graph consists of N vertices and M edges. Each vertex of the graph has an unique index from 1 to N, also each edge of the graph has an unique index from 1 to M. Also Chef has Q pairs of integers: Li, Ri (1 ≤ Li ≤ Ri ≤ M). For each pair Li, Ri, Chef wants to know: how many connected components will contain graph G if Chef erase all the edges f
