哈哈哈

直接上代码
#include <bits/stdc++.h>
using namespace std;
long long n,ans,j = 1;
int main(){
cin>>n;
if(n%2==1){
ans = -1;
cout<<ans;
return 0;
}
while(pow(2,j)<10000000){
if(pow(2,j)==n){
ans = n;
cout<<ans;
return 0;
}
j++;

}
while(n>=2){
	int tmp = 1;
	while(pow(2,tmp)<=n){
		tmp+=1;
	}
	ans = pow(2,(tmp-1));
	n-=ans;
	cout<<ans<<" ";
}
return 0;

}
