Can anyone suggest an input which this code gives the wrong output?

#1 
#include <bits/stdc++.h>
#include <math.h>
using namespace std;

int main(){

    int t;
    long long int f,i,k;
    cin >> t;
    while(t--){
        
        bool found = false;
        bool dont = false;
        cin >> f;
        if((f%2==1) || (f<=0) || (f>=pow(2,30))){
            cout << -1 << endl;
            continue;
        }
        for(long long int p=2; p<=pow(2,30); p<<=1){
            if(p==f){
                dont = true;
            }
        }

        if(!dont){
            for(i=29; i>=0; i--){
                k = pow(2,i+1);
                if(((f%k) == 0) && (f!=k) && (pow(2,i)!=(f/2) - pow(2,i))){
                    found = true;
                    break;
                    
                }
            }
        }
        

        if(found){
            cout << 0 << ' ' <<  pow(2,i) << ' ' << (f/2) - pow(2,i) << endl;
            
        }else{
            cout << -1 << endl;
        }
        
    }


}
