A-我会开摆

#include<bits/stdc++.h>
using namespace std;
typedef long long LL;
typedef pair<LL,LL> PII;
const LL MAXN=1e18,MINN=-MAXN,INF=0x3f3f3f3f;
const LL N=2e6+10,M=3023;
const LL mod=100000007;
const double PI=3.1415926535;
#define endl '\n'
char a[M][M];
int main()
{
    //cin.tie(0); cout.tie(0); ios::sync_with_stdio(false);
    LL T=1;
    cin>>T;
    while(T--)
    {
        for(int i=1;i<=4;i++)
        {
            for(int j=1;j<=4;j++)
            {
                cin>>a[i][j];
            }
        }
        bool flag=false;
        for(int i=1;i<=3;i++)
        {
            for(int j=1;j<=3;j++)
            {
                if(a[i][j]==a[i+1][j]&&a[i][j]==a[i][j+1]&&a[i][j]==a[i+1][j+1])
                {
                    flag=true;
                    break;
                }
            }
        }
        if(flag==false) cout<<"No"<<endl;
        else cout<<"Yes"<<endl;
    }
