关于#c语言#的问题，请各位专家解答！

#include<bits/stdc++.h>
using namespace std;
int main()
{
    int n;
    cin>>n;
    for(int x=1;x<=n;x++)
    {
        string s;
        cin>>s;
        int len=s.length();
        int sa=0;
        for(int i=0;i<len;i++)
        {
           if(s[i]=='L'&&s[i-1]=='L'&&s[i+1]=='L') 
           {
               cout<<"NO";
               goto next;
           }
           else if(s[i]=='A') sa++;
           
        }
        if(sa>=2) cout<<"NO";
        else cout<<"YES";
        next:cout<<endl;
    }
