将每个格子标记为 x*n*n+y*n+z  每个格子会有一个独特的编号  将它放入vector中  去重  我一开始用 set 超时

#include <cstdio>
#include <cstring>
#include <vector>
#include <set>
#include <algorithm>

using namespace std;

int main()
{
    vector<int> a;
    int t,n,m;
    scanf("%d",&t);
    while(t--)
    {
        a.clear();
        scanf("%d%d%*c",&n,&m);
        for(int i = 0; i < m; i++)
        {
            char c,d;
            int u,v;
            scanf("%c%*c%d%*c%c%*c%d%*c",&c,&u,&d,&v);
            if(c == 'X' && d == 'Y')
                for(int i = 1; i <= n; i++)
                    a.push_back(u*n*n+v*n+i);
            else if(c == 'X' && d == 'Z')
                for(int i = 1; i <= n; i++)
                    a.push_back(u*n*n+i*n+v);
            else if(c == 'Y' && d == 'X')
                for(int i = 1; i <= n; i++)
                    a.push_back(v*n*n+u*n+i);
            else if(c == 'Y' && d == 'Z')
                for(int i = 1; i <= n; i++)
                    a.push_back(i*n*n+u*n+v);
            else if(c == 'Z' && d == 'Y')
                for(int i = 1; i <= n; i++)
                    a.push_back(i*n*n+v*n+u);
            else if(c == 'Z' && d == 'X')
                for(int i = 1; i <= n; i++)
                    a.push_back(v*n*n+i*n+u);
        }
        sort(a.begin(), a.end());
        int u = unique(a.begin(), a.end())-a.begin();
        printf("%d\n",u);
    }
    return 0;
}
