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).
Constraints
- 2 \leq N \leq 2 \times 10^5
- 1 \leq a_i,b_i \leq N
- The given graph is a tree.
