题目描述
You are given a cactus graph, in this graph each edge lies on at most one simple cycle.
It is given as m edges ai,bi , weight of i -th edge is i .
Let's call a path in cactus increasing if the weights of edges on this path are increasing.
Let's call a pair of vertices (u,v) happy if there exists an increasing path that starts in u and ends in v .
For each vertex u find the number of other vertices v , such that pair (u,v) is happy.
输入格式
The first line of input contains two integers n,m ( 1≤n,m≤500000 ): the number of vertices and edges in the given cactus.
The next m lines contain a description of cactus edges, i -th of them contain two integers ai,bi ( 1≤ai,bi≤n,ai=bi ).
It is guaranteed that there are no multiple edges and the graph is connected.
输出格式
Print n integers, required values for vertices 1,2,…,n .
