90分求调

rt,求调，最好在此基础上改

#include<bits/stdc++.h>
using namespace std;
string s;
char c;
int a1,b1;
int a2,b2;
int main()
{
    while(true)
    {
        cin>>c;
        if(c=='E') break;
        s+=c;
    }
    int n=s.size();
    if(n==0) cout<<"0:0\n\n0:0";
    for(int i=0;i<n;i++)
    {
        if(s[i]=='W') a1++;
        else b1++;
        if(abs(a1-b1)>=2&&max(a1,b1)>=11)
        {
            cout<<a1<<":"<<b1<<endl;
            a1=0;
            b1=0;
        }
    }
    if(a1!=0||b1!=0) cout<<a1<<":"<<b1<<endl;
    cout<<endl;
    for(int i=0;i<n;i++)
    {
        if(s[i]=='W') a2++;
        else b2++;
        if(abs(a2-b2)>=2&&max(a2,b2)>=21)
        {
            cout<<a2<<":"<<b2<<endl;
            a2=0;
            b2=0;
        }
    }
    if(a2!=0||b2!=0) cout<<a2<<":"<<b2<<endl;
    return 0;
} 

别用很难理解的东西
