Problem type

There is a tree with vertices, numbered . For each , the -th edge connects Vertex and .

Taro has decided to paint each vertex in white or black, so that any black vertex can be reached from any other black vertex by passing through only black vertices.

You are given a positive integer . For each , answer the following question:

• Assuming that Vertex has to be black, find the number of ways in which the vertices can be painted, modulo .

Constraints

• All values in input are integers.
• The given graph is a tree.

Input Specification

The first line will contain two integers and .

The next lines will each contain two integers and .

Output Specification

Print lines. The -th line should contain the answer to the following question:

• Assuming that Vertex has to be black, find the number of ways in which the vertices can be painted, modulo .
