这题目有问题啊

#include<bits/stdc++.h>
using namespace std;
long long n;
string a;
int main(){
    cin>>n;
    for(long long i=1;i<=n;i++){
    	cin>>a;
    	long long sizee=a.size();
    	bool p=1;
    	for(long long j=0;j<=sizee/2;j++)
    		if(a[j]!=a[sizee-j-1]){
    			p=0;
    			break;
			}
		if(p==1)
			cout<<"No"<<endl;
		else
			cout<<"Yes"<<endl;
	}
    return 0;
}
