这串代码本身非常垃圾，但是由于之前刚学了下怎么分割字符串，所以我这边也试了下，在本地运行是可以的。但是交上去就RE了 我感觉好奇怪，请教下大佬。

#include <iostream>
#include <string>
#include <algorithm>
using namespace std;

int computeMoney(int final, int s_class, const string& isLeader, const string& isStudent, int paper) {
	int money = 0;
	if (final > 80 && paper >= 1) {
		money += 8000;
	} 
	if (final > 85 && s_class > 80) {
		money += 4000;
	}
	if (final > 90) {
		money += 2000;
	}
	if (final > 85 && isStudent == "Y") {
		money += 1000;
	}
	if (s_class > 80 && isLeader == "Y") {
		money += 850;
	}
	return money;
}

int main() {
    int n;
    cin >> n;
    cin.ignore();
    int sum = 0;
    int maxMoney = 0;
    string maxStudent = "";
    while (n--) {
    	string str;
    	getline(cin, str);
    	size_t space1 = str.find(' ');
    	size_t space2 = str.find(' ', space1 + 1);
    	size_t space3 = str.find(' ', space2 + 1);
    	size_t space4 = str.find(' ', space3 + 1);
    	size_t space5 = str.find(' ', space4 + 1);
    	
    	string name = str.substr(0, space1);
    	int final = stoi(str.substr(space1 + 1, space2 - space1 - 1));
    	int s_class = stoi(str.substr(space2 + 1, space3 - space2 - 1));
    	string isLeader = str.substr(space3 + 1, space4 - space3 - 1);
    	string isStudent = str.substr(space4 + 1, space5 - space4 - 1);
    	int paper = stoi(str.substr(space5 + 1));
    	
    	int money = computeMoney(final, s_class, isLeader, isStudent, paper);
    	
    	if (money > maxMoney) {
    		maxMoney = money;
    		maxStudent = name;
		}
		
		sum += money;
	}
	
	cout << maxStudent << endl;
	cout << maxMoney << endl;
	cout << sum << endl;
    return 0;
