样例过了，AC1个RE4个，求解

#include <iostream>
#include <math.h>
using namespace std;



struct student {
	string name;
	int a, b, c;


};

bool canbe(student s1, student s2) {
	if (abs(s1.a - s2.a) <= 5 && abs(s1.b - s2.b) <= 5 && abs(s1.c - s2.c) <= 5
	        && abs(s1.a + s1.b + s1.c - s2.c - s2.b - s2.a) <= 10 )
		return 1;
	return 0;
}

student stu[1005];
string cp[1005][2];

int main() {
	int n;
	cin >> n;

	int cp_p = 0;
	for (int i = 0; i < n; i++) {
		cin >> stu[i].name >> stu[i].a >> stu[i].b >> stu[i].c;
	}
	for (int i = 0; i < n; i++) {
		for (int j = i + 1; j < n; j++) {
			if (canbe(stu[i], stu[j])) {
				if (stu[i].name < stu[j].name) {
					cp[cp_p][0] = stu[i].name;
					cp[cp_p][1] = stu[j].name;
				} else {
					cp[cp_p][0] = stu[j].name;
					cp[cp_p][1] = stu[i].name;
				}
				cp_p++;
			}
		}
	}

	for (int i = 0; i < cp_p; i++) {
		cout << cp[i][0] << " " << cp[i][1] << endl;
	}
	return 0;
}
