Let us say you randomly choose 'N' non-negative integers less than 'M' and put them in an array 'A'.


Find the probability that 'A' is sorted in non-decreasing order.


The answer should be found modulo 10^9 + 7. Formally, let M = 10^9 + 7. It can be shown that the answer can be expressed as an irreducible fraction p/q, where p and q are integers and q !≡ 0 (mod M). Output the integer equal to p * (q^-1) mod M. In other words, output such an integer x that 0 <= x < M and x * q ≡ p (mod M).


For Example :
Let 'N' = 3, 'M' = 3.
There are 27 possible final arrays.
10 of them are sorted in non-decreasing order: [ '0, 0, 0' ], [ '1, 1, 1' ], [ '2, 2, 2' ], [ '0, 1, 2' ], [ '0, 0, 1' ], [ '0, 1, 1' ], [ '0, 0, 2' ], [ '0, 2, 2' ], [ '1, 1, 2' ], [ '1, 2, 2' ].
Thus the probability needed is '(10 / 27) % (10^9 + 7) = 703703709'.

Given an undirected graph of V vertices and E edges. Your task is to find all the bridges in the given undirected graph. A bridge in any graph is defined as an edge which, when removed, makes the graph disconnected (or more precisely, increases the number of connected components in the graph).

For Example :

If the given graph is :

graph

Then the edge between 0 and 4 is the bridge because if the edge between 0 and 4 is removed, then there will be no path left to reach from 0 to 4.and makes the graph disconnected, and increases the number of connected components.

Note :

There are no self-loops(an edge connecting the vertex to itself) in the given graph.

There are no parallel edges i.e no two vertices are directly connected by more than 1 edge.
