/**
 * Author: Yuhao Yao
 * Date: 23-05-11
 * Description: Modular integer with $mod \le 2^{31} - 1$. Note that there are several advantages to use this code:
   1. You do not need to keep writing $\%\, mod$;
   2. It is good to use this struct when doing Gaussian Elimination / Fast Walsh-Hadamard Transform;
   3. Sometimes the input number is greater than $mod$ and this code handles it.
  Do not write things like $mint\{1 / 3\}.pow(10)$ since $1 / 3$ simply equals $0$.
  Do not write things like $mint\{a * b\}$ where $a$ and $b$ are int since you might first have integer overflow.
 * Usage: Define the followings globally:
   const int mod = 998244353;
   using mint = MInt<mod>;
 * Status: tested on https://ac.nowcoder.com/acm/contest/33191/F.
