#include<bits/stdc++.h>
using namespace std;

}
}
int main(){
int n;
cin >> n;
for(int i = 2; i <= n; i++){
int x;
cin >> x;
g[x].push_back(i);
}
// cout << st[1].size() << endl;
dfs(1);
int crr = 0;
for(auto it = st[1].rbegin(); it != st[1].rend(); it++){
crr++;
cout << crr << ' ';
for(int i = 0; i < *it-1; i++){
crr+=2;
cout << crr << ' ';
}
}
}
这程序好像有点Bug,我给组数据试试?
