A directed acyclic graph consists of n nodes and m edges. The nodes are numbered 1,2,\dots,n.
Calculate for each node the number of nodes you can reach from that node (including the node itself).
The first input line has two integers n and m: the number of nodes and edges.
Then there are m lines describing the edges. Each line has two distinct integers a and b: there is an edge from node a to node b.
Print n integers: for each node the number of reachable nodes.
- 1 \le n \le 5 \cdot 10^4
- 1 \le m \le 10^5
