我测试过好多遍了，看了帖子，也上必应查过了，实在想不出来，路过的大佬提点一下吧，笔芯

#include <cmath>
#include <cstdio>
#include <iostream>
#include <vector>
using namespace std;
vector<bool> record;

void printScore(int n) {
	int a = 0, b = 0, f = 0;
	for (int i = 0; i < record.size(); i++) {
		record[i] ? a++ : b++;
		if ((a >= n || b >= n) && abs(a - b) >= 2) {
			printf("%d:%d\n", a, b);
			a = b = 0;
			f++;
		}
	}
	if (!f || a + b != 0) printf("%d:%d\n", a, b);
}

int main() {
	char temp;
	while ((temp = getchar()) != 'E')
		if (temp == 'W') record.push_back(1);
		else if (temp == 'L') record.push_back(0);
	printScore(11);
	cout << endl;
	printScore(21);
	return 0;
}
