20分，求调。输出结果和测试点2一样，但判错，不知道是哪里出问题了```cpp

using namespace std;

#include<iostream>
#include<cstdio>
#include<sstream>

int main()
{
    char c;
    int w1=0,w2=0,l1=0,l2=0;
    stringstream s1,s2;
    
    while(1)
    {
        c=getchar();
        
        if (c=='\n')
            continue;
        else if(c=='E')
        {
            s1<<w1<<":"<<l1<<endl;
            s2<<w2<<":"<<l2<<endl;
            break;
        }
        
        if(c=='W')
            w1++,w2++;
        else
            l1++,l2++;
            
        if((w1>=11||l1>=11)&&(w1-l1>=2||l1-w1>=2))
        {
            s1<<w1<<":"<<l1<<endl;
            w1=0;l1=0;
        }
        
        if((w2>=21||l2>=21)&&(w2-l2>=2||l2-w2>=2))
