Minimum and maximum connected component

An undirected graph is given. Find the size of its smallest and largest connected components.

Input

The first line contains two positive integers $n$ and $m(1\le n,m\le 10000)$ — the number of vertices and edges of the graph. Each of the following $m$ lines contains two integers $a_i$ and $b_i(1\le a_i,b_i\le n)$ — the description of an undirected edge.

Output

Print on one line the size of the smallest and largest connected components of the graph.
