改了还是只有80分啊
```cpp
#include<bits/stdc++.h>
using namespace std;
int n,step=-1;
int a[1000020];
void hh(int t)
{
int c;
step++;
if(t>=1)
{
c=t%2;
t=t/2;
if(c==1)
{
a[step]++;
}
hh(t);
}
else
{
for(int i=step;i>=0;i--)
{
if(a[i]==1)
{
cout<<pow(2,i)<<" ";
}
}
cout<<endl;
}
}
int main()
{
cin>>n;
if(n%2==0)
{
hh(n);
}
else
{
cout<<"-1"<<endl;
}
return 0;
}
```

洛谷在线IED 测的把pow(2,i)改成int(pow(2,i))试试
