[abc229_e]Graph Destruction
Problem Statement
Given is an undirected graph with vertices and edges.
Edge connects Vertices and .
We will erase Vertices one by one.
Here, erasing Vertex means deleting Vertex and all edges incident to Vertex from the graph.
For each , how many connected components does the graph have when vertices up to Vertex are deleted?
Constraints
- $0 \\leq M \\leq \\min(\\frac{N(N-1)}{2} , 2 \\times 10^5 )$
- if .
- All values in input are integers.
Input
Input is given from Standard Input in the following format:
Output
Print lines.
The -th line should contain the number of connected components in the graph when vertices up to Vertex are deleted.
