题目描述
Marin wants you to count number of permutations that are beautiful. A beautiful permutation of length n is a permutation that has the following property: $$$$ \gcd (1 \cdot p_1, , 2 \cdot p_2, , \dots, , n \cdot p_n) > 1, $$ where gcd is the greatest common divisor.
A permutation is an array consisting of n distinct integers from 1 to n in arbitrary order. For example, \[2,3,1,5,4\] is a permutation, but \[1,2,2\] is not a permutation ( 2 appears twice in the array) and \[1,3, 4\] is also not a permutation ( n=3 but there is 4$$ in the array).
输入格式
The first line contains one integer t ( 1≤t≤103 ) — the number of test cases.
Each test case consists of one line containing one integer n ( 1≤n≤103 ).
输出格式
For each test case, print one integer — number of beautiful permutations. Because the answer can be very big, please print the answer modulo 998244353 .

7 1 2 3 4 5 6 1000
输出#1
0 1 0 4 0 36 665702330
说明/提示
In first test case, we only have one permutation which is [1] but it is not beautiful because gcd(1⋅1)=1 .
In second test case, we only have one beautiful permutation which is [2,1] because gcd(1⋅2,2⋅1)=2 .
