Chef and Bipartite Graphs

CodeChefOpen on judge ↗

Chef is very interested in studying biparite graphs. Today he wants to construct a bipartite graph with n vertices each, on the two parts, and with total number of edges equal to m. The vertices on the left are numbered from 1 to n. And the vertices on the right are also numbered from 1 to n. He also wants the degree of every vertex to be greater than or equal to d, and to be lesser than or equal
