My issue

Why 336 is wrong answer for 3 digit??

My code

#include <bits/stdc++.h>
using namespace std;

int main() {
	// your code goes here
	int t;
	cin>>t;
	while(t--){
	    int ans = 3, t = 3;
	    int d;
	    cin>>d;
	    for(int i=1;i<d;i++){
	        ans*=10;
	        ans+=3;
	    }
	    if(ans%9==0){
	        cout<<ans+3<<endl;
	    }
	    else{
	        cout<<ans<<endl;
	    }
	}
	return 0;
}
