Problem Statement

We have a tree with NN vertices numbered 11 to NN. The ii-th edge in this tree connects Vertex aia_i and bib_i. For each k=1,...,Nk=1, ..., N, solve the problem below:

  • Consider writing a number on each vertex in the tree in the following manner:- First, write 11 on Vertex kk.
    • Then, for each of the numbers 2,...,N2, ..., 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 (109+7)(10^9+7).

Constraints

  • 2N2×1052 \leq N \leq 2 \times 10^5
  • 1ai,biN1 \leq a_i,b_i \leq N
  • The given graph is a tree.

Input

For k=1k=1, there are two ways in which we can write the numbers on the vertices, as follows:

  • Writing 1,2,31, 2, 3 on Vertex 1,2,31, 2, 3, respectively
  • Writing 1,3,21, 3, 2 on Vertex 1,2,31, 2, 3, respectively
