Educational DP Contest AtCoder V - Subtree
View as PDFThere 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
.

Explanation For Sample 1
There are seven ways to paint the vertices, as shown in the figure below. Among them, there are three ways such that Vertex  is black, four ways such that Vertex 
 is black and three ways such that Vertex 
 is black.
