#include<iostream>
using namespace std;

int main(){
    long long n;
    cin>>n;
    if(n%2==1){//加特判
        cout<<-1;
        return 0;
    }
    long long chu=1;
    for(chu=1;chu<=n;chu*=2) chu*=2;//得出基准数
    //cout<<chu;
    while (n!=0){
    	if(chu<=n){
    		cout<<chu<<' ';
    		n-=chu;
		}
		if(chu==0) return 0;
		chu/=2;
	}
}
