문제

The NN cows of Farmer John's Circus (1N1051 \leq N \leq 10^5) are preparing their upcoming acts. The acts all take place on a tree with vertices labeled 1N1\ldots N. The "starting state" of an act is defined by a number 1KN1 \leq K \leq N and an assignment of cows 1K1\dots K to the vertices of the tree, so that no two cows are located at the same vertex.

In an act, the cows make an arbitrarily large number of "moves." In a move, a single cow moves from her current vertex to an unoccupied adjacent vertex. Two starting states are said to be equivalent if one may be reached from the other by some sequence of moves.

For each 1KN1 \leq K \leq N, help the cows determine the number of equivalence classes of starting states: that is, the maximum number of starting states they can pick such that no two are equivalent. Since these numbers may be very large, output their remainders modulo 109+710^9 + 7.

입력

Line 11 contains NN.

Lines 2iN2\le i\le N each contain two integers aia_i and bib_i denoting an edge between aia_i and bib_i in the tree.

출력

For each 1iN,1\le i\le N, the ii-th line of output should contain the answer for K=iK=i modulo 109+710^9+7.
