题目描述

Will shares a psychic connection with the Upside Down Monster, so everything the monster knows, Will knows. Suddenly, he started drawing, page after page, non-stop. Joyce, his mom, and Chief Hopper put the drawings together, and they realized, it's a labeled tree!

A tree is a connected acyclic graph. Will's tree has nn vertices. Joyce and Hopper don't know what that means, so they're investigating this tree and similar trees. For each kk such that 0<=k<=n10<=k<=n-1 , they're going to investigate all labeled trees with nn vertices that share exactly kk edges with Will's tree. Two labeled trees are different if and only if there's a pair of vertices (v,u)(v,u) such that there's an edge between vv and uu in one tree and not in the other one.

Hopper and Joyce want to know how much work they have to do, so they asked you to tell them the number of labeled trees with nn vertices that share exactly kk edges with Will's tree, for each kk . The answer could be very large, so they only asked you to tell them the answers modulo 1000000007=109+71000000007=10^{9}+7 .

输入格式

The first line of input contains a single integer nn ( 2<=n<=1002<=n<=100 ) — the size of the tree.

The next n1n-1 lines contain the edges of Will's tree. Each line contains two integers vv and uu ( 1<=v,u<=n1<=v,u<=n , vuv≠u ), endpoints of an edge. It is guaranteed that the given graph is a tree.

输出格式

Print nn integers in one line. ii -th integer should be the number of the number of labeled trees with nn vertices that share exactly i1i-1 edges with Will's tree, modulo 1000000007=109+71000000007=10^{9}+7 .
