Eulerian Subgraphs

CSESAdvanced TechniquesOpen on judge ↗

You are given an undirected graph that has n nodes and m edges. We consider subgraphs that have all nodes of the original graph and some of its edges. A subgraph is called Eulerian if each node has even degree. Your task is to count the number of Eulerian subgraphs modulo 10^9+7. Input The first input line has two integers n and m: the number of nodes and edges. The nodes are numbered 1,2,\dot
