题目描述

Marin wants you to count number of permutations that are beautiful. A beautiful permutation of length nn 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\\gcd is the greatest common divisor.

A permutation is an array consisting of nn distinct integers from 11 to nn in arbitrary order. For example, \[2,3,1,5,4\] is a permutation, but \[1,2,2\] is not a permutation ( 22 appears twice in the array) and \[1,3, 4\] is also not a permutation ( n=3n=3 but there is 44$$ in the array).

输入格式

The first line contains one integer tt ( 1t1031 \le t \le 10^3 ) — the number of test cases.

Each test case consists of one line containing one integer nn ( 1n1031 \le n \le 10^3 ).

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 998244353998\,244\,353 .

说明/提示

In first test case, we only have one permutation which is [1][1] but it is not beautiful because gcd(11)=1\gcd(1 \cdot 1) = 1 .

In second test case, we only have one beautiful permutation which is [2,1][2, 1] because gcd(12,21)=2\gcd(1 \cdot 2, 2 \cdot 1) = 2 .
