CSESMathematicsOpen on judge ↗

Consider a directed graph that has n nodes and m edges. Your task is to count the number of paths from node 1 to node n with exactly k edges. Input The first input line contains three integers n, m and k: the number of nodes and edges, and the length of the path. The nodes are numbered 1,2,\dots,n. Then, there are m lines describing the edges. Each line contains two integers a and b: there is a
