Problem Statement
We have a tree with N vertices numbered 1 to N. The i-th edge in this tree connects Vertex a_i and b_i.
For each k=1, ..., N, solve the problem below:
- Consider writing a number on each vertex in the tree in the following manner:
- First, write 1 on Vertex k.
- Then, for each of the numbers 2, ..., N in this order, write the number on the vertex chosen as follows:
-
Choose a vertex that still does not have a number written on it and is adjacent to a vertex with a number already written on it. If there are multiple such vertices, choose one of them at random.
-
Find the number of ways in which we can write the numbers on the vertices, modulo (10^9+7).
Input
Input is given from Standard Input in the following format:
N
a_1 b_1
:
a_{N-1} b_{N-1}
Output
For each k=1, 2, ..., N in this order, print a line containing the answer to the problem.
Constraints
- $2 \leq N \leq 2 \times 10^5$
- $1 \leq a_i,b_i \leq N$
- The given graph is a tree.
