参考代码
```cpp
#include<iostream>
#include<string>
#include<cmath>
using namespace std;
char t;
int l1,w1,l2,w2,a[10000],b[10000];
int main()
{
int num=0;
do{
cin>>t;
if(t=='W'){
w1++;
w2++;
}
else if(t=='L'){
l1++;
l2++;
}
if((w1>=11||l1>=11)&&abs(w1-l1)>=2){
cout<<w1<<":"<<l1<<endl;
w1=0;
l1=0;
}
if((w2>=21||l2>=21)&&abs(w2-l2)>=2){
a[++num]=w2;
b[num]=l2;
w2=0;
l2=0;
}
}while(t!='E');
cout<<w1<<":"<<l1<<endl<<endl;
for(int i=1;i<=num;i++){
cout<<a[i]<<":"<<b[i]<<endl;
}
cout<<w2<<":"<<l2;
return 0;
}
```
