@[Bramble_Marshall](/user/1059049) 变量名 a 和结构体名重复了，改一下就好了。
```
#include <bits/stdc++.h>
using namespace std;
const int N = 1e2+5;
string input() {
char t;
string ans = "";
t = getchar();
while (t == ' ' || t == '\n')
t = getchar();
while (t != EOF && t != ' ' && t != '\n') {
ans += t;
t = getchar();
}
return ans;
}
void prints(string iut) {
long long n = iut.size();
for (int i = 0; i <= n; i++)
putchar(iut[i]);
}
struct node {
string n;
int d;
} a[N];
bool cmp(node a, node b) {
return a.d < b.d;
}
int main() {
int m, x, b, c;
scanf("%d", &m);
for (int i = 1; i <= m; i++) {
a[i].n = input();
scanf("%d %d %d", &x, &b, &c);
a[i].d = ((x * 1e2 + b) * 1e2 + c) * 1e3 + 100 - i;
}
sort(a + 1, a + m + 1, cmp);
for (int i = 1; i <= 3; i++)
prints(a[i].n);
return 0;
}
