你好逊啊还要22行

诶确实为什么这么复杂，需要数组吗

您太 **强** 了啊，无敌了啊，22 行 **就** 解决了啊

你好菜啊。
```cpp
#include<bits/stdc++.h>
int main(){
int n; scanf("%d",&n); if(n&1) puts("-1"); else
for(int i=30;i>=1;--i) if(n&(1<<i)) printf("%d ",1<<i);
}
```

22行有啥好炫耀的啊

```
#include<iostream>
int main(){int n,i=1<<30;std::cin>>n;if(n&1)puts("-1");else while(~(i=i/2)&1)if(n&i)std::cout<<i<<" ";}
```
为什么要像你那样复杂？

```cpp
#include <bits/stdc++.h>
using namespace std;
int main(){
int n; cin >> n; if(n%2==1) cout << -1;
else while(n){cout << pow(2,int(log(n)/log(2))) << " ";n-=pow(2,int(log(n)/log(2)));}
}
```

~~cin换scanf还能再少一行~~
