    思路
    就按照 它的三种方式 设计 comp 函数 然后快排就好了

    但是 如果用 c++ 中的 string 保存名字的话 就会超时

    所以 用 c 里面的 char *s 就可以过

    AC代码

    #include <cstdio>
    #include <cstring>
    #include <ctype.h>
    #include <cstdlib>
    #include <cmath>
    #include <climits>
    #include <ctime>
    #include <iostream>
    #include <algorithm>
    #include <deque>
    #include <vector>
    #include <queue>
    #include <string>
    #include <map>
    #include <stack>
    #include <set>
    #include <numeric>
    #include <sstream>
    #include <iomanip>
    #include <limits>
    
    #define CLR(a) memset(a, 0, sizeof(a))
    #define pb push_back

    }

            return x.id < y.id;
        return strcmp(x.name, y.name) > 0 ? 0 : 1;
    }

        return x.g < y.g;
    }
    
    int main()
    {
        int n, c;
        scanf("%d%d", &n, &c);
        for (int i = 0; i < n; i++)
            scanf("%d%s%d", &a[i].id, &a[i].name, &a[i].g);
        if (c == 1)
            sort(a, a + n, comp_1);
        else if (c == 2)
            sort(a, a + n, comp_2);
        else if (c == 3)
            sort(a, a + n, comp_3);
        for (int i = 0; i < n; i++)
            printf("%06d %s %d
    ", a[i].id, a[i].name, a[i].g);
    }
