CSESTree AlgorithmsOpen on judge ↗

You are given a tree consisting of n nodes. Your task is to process q queries of the form: what is the distance between nodes a and b? Input The first input line contains two integers n and q: the number of nodes and queries. The nodes are numbered 1,2,\ldots,n. Then there are n-1 lines describing the edges. Each line contains two integers a and b: there is an edge between nodes a and b. Fina
