#include<bits/stdc++.h>
using namespace std;
int main()
{
int u,v;
cin>>u>>v;
int tu=u,tv=v;
set<int> s;
while(tu)
{
tu=tu/2;
s.insert(tu);
if(tu==v)
{
cout<<-1<<endl;
return 0;
}
}
while(tv)
{
tv=tv/2;
s.insert(tv);
if(tv==u)
{
cout<<-1<<endl;
return 0;
}
}
set<int> ans;
function<void(int)> solve=[&](int now)
{
if(s.contains(now))
{
solve(now*2);
solve(now*2+1);
}
else ans.insert(now);
};
solve(1);
for(auto z:ans)
cout<<z<<" ";
return 0;
}
这程序好像有点Bug，我给组数据试试？
