Problem Statement

You are given an integer sequence of length n+1, a_1,a_2,...,a_{n+1}, which consists of the n integers 1,...,n.
It is known that each of the n integers 1,...,n appears at least once in this sequence.

For each integer k=1,...,n+1, find the number of the different subsequences (not necessarily contiguous) of the given sequence with length k, modulo 10^9+7.

Notes

If the contents of two subsequences are the same, they are not separately counted even if they originate from different positions in the original sequence.

A subsequence of a sequence a with length k is a sequence obtained by selecting k of the elements of a and arranging them without changing their relative order. For example, the sequences 1,3,5 and 1,2,3 are subsequences of 1,2,3,4,5, while 3,1,2 and 1,10,100 are not.

Constraints

1 \leq n \leq 10^5

1 \leq a_i \leq n

Each of the integers 1,...,n appears in the sequence.

n and a_i are integers.

Input

Input is given from Standard Input in the following format:

n
a_1 a_2 ... a_{n+1}

Output

Print n+1 lines.
The k-th line should contain the number of the different subsequences of the given sequence with length k, modulo 10^9+7.

Be sure to print the numbers modulo 10^9+7.

Solution in Python (3.4.3) (judge verdict: Wrong Answer)

import scipy.misc as scm
import sys

n=int(input())
s=[int(i) for i in input().split()]
for i in range(1,n+1):
    k=s.count(i)
    if k==2:
        a=s.index(i)
        b=s.index(i,a+1)
        print(a,b)

for i in range(1,n+2):
    print(scm.comb(n+1,i,1)-scm.comb(a+n-b,i-1,1))
