有大佬能指点修改下代码吗？

#include<iostream>
#include<string>
using namespace std;
char a[2510] ;
int main()
{
	for(int i=1;i<=2500;i++)
	{
		cin>>a[i];
		if(a[i]=='E')
		{
			break;
		}
	}
	int win=0,low=0;
	for(int i=1;i<=2500;i++)
	{
		if(a[i]=='W')
		{
			win++;
		}
		if(a[i]=='L')
		{
			low++;
		}
		if(win==11||low==11)
		{
			cout<<win<<":"<<low<<endl;
			win=0;
			low=0;
		}
		
	}
	if(win!=0||low!=0)
	{
		cout<<win<<":"<<low<<endl;
	}
	cout<<"    "<<endl;
	win=0;
	low=0;
		for(int i=1;i<=2500;i++)
	{
		if(a[i]=='W')
		{
			win++;
		}
		if(a[i]=='L')
		{
			low++;
		}
		if(win==21||low==21)
		{
			cout<<win<<":"<<low<<endl;
			win=0;
			low=0;
		}
		
	}
		if(win!=0||low!=0)
	{
		cout<<win<<":"<<low<<endl;
	}
	
	
}
