```
long long n;
long long i = 1;
```
这两个改成int类型
```
cout << pow(2, i) << " ";
```
改成
```
cout << (int)pow(2, i) << " ";
```

废话不多说，看代码
```cpp
#include<bits/stdc++.h>
#define ll long long
using namespace std;
int a[100000];
int main() {
int n, t=0;
scanf("%d",&n);
while(n){
a[++t] = n%2;
n = n/2;
}
if(a[1]==1) {
cout << -1;
return 0;
}
else{
for(int i = t; i >= 1; i--){
if(a[i]==0) continue;
int tmp = pow(2,i-1);
cout << a[i] * tmp << ' ';
}
}
return 0;
}
```
