模二运算 理论上是mo2任意维数
#include <iostream>
#include <algorithm>
using namespace std;
long n,a[255][255];
int i,j;
void input()
{
int row,col;
cout<<"请输入维数:\n";
cin>>n;
cout<<"请输入行i数:\n";
cin>>row;
cout<<"请输入列j数:\n";
cin>>col;
cout<<"\n\t------in------\n";
for (long i=1;i<=row;i++) {
cout<<":";
for(j=1;j<=col;j++)
cin>>a[i][j];
}
