Kaaleppi has created the following puzzle:
Given an integer n, construct a permutation of numbers 1,2,\ldots,n such that there are no adjacent values whose difference is 1.
For example, when n = 4, there are 2 solutions: (2, 4, 1, 3) and (3, 1, 4, 2).
Your task is to calculate the number of solutions for Kaaleppi's puzzle for given n values. The answer may be big so please output it modulo 10^9+7.
Input
The first input line contains an integer t: the number of test cases.
After this, t lines follow. Each line contains an integer n.
Output
For each test case, output the number of solutions for Kaaleppi's puzzle modulo 10^9+7.
Constraints
- 1 \le t \le 20
- 1 \le n \le 1000
Example
Input:
3 4 9 123
Output:
