You are given a tree consisting of n nodes, and m paths in the tree.
Your task is to calculate for each node the number of paths containing that node.
The first input line contains integers n and m: the number of nodes and paths. 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.
Finally, there are m lines describing the paths. Each line contains two integers a and b: there is a path between nodes a and b.
Print n integers: for each node 1,2,\ldots,n, the number of paths containing that node.
- 1 \le n, m \le 2 \cdot 10^5
- 1 \le a,b \le n
