不求AC代码，求改，代码应该不算复杂 a表示第一个人的分数，b是第二个人的，函数判断是否超过两分（不会绝对值函数，

# include<bits/stdc++.h>
using namespace std;
int a, b, x;
bool a_b(int x, int y){
	if(x > y){
		if(x - y >= 2) return true;
		else return false;
	}
	if(x < y){
		if(y - x >= 2) return true;
		else return false;
	}
	if(x == y) return false;
}
void C(){
	cout << a << ":" << b << endl;
}
int main(){
	string s1, s;
	while(1){
		cin >> s1;
		s += s1;
		if(s[s.length() - 1] == 'E') break;
	}
	for(int i = 0; i < s.length() - 1; i++){
		if(s[i] == 'W') a++;
		if(s[i] == 'L') b++;
		if(a + b >= 11){
			if(a_b(a, b)){
			    C();
				a = 0, b = 0;	
			}else{
				x = 1;
			} 
			if(x == 1){
				if(a_b(a, b)){
					C();
					x = 0, a = 0, b = 0;
				}
			} 
		}
	}
	C();
	cout << endl;
	a = 0, b = 0, x = 0;
	for(int i = 0; i < s.length() - 1; i++){
