Hello!
I have tryed to solve 1022 on C++:

#include<iostream>
#include<vector>
#include<algorithm>
using namespace std;

struct member
{
        int latency;
        int number;
        vector<int>child;
        member() {latency=0; child.resize(0);}
};

struct member_less : public binary_function<member, member, bool>
{
        bool operator()(const member& m1, const member& m2) const
        { return m1.latency < m2.latency; };
};

int main()
{
        int numb_of_members;
        cin >> numb_of_members;
        vector<member>mosk(numb_of_members);
        for (int i=0;i<numb_of_members;i++)
        {
                mosk[i].number=i;
                int buf;
                cin >> buf;
                while(buf!=0)
                {
                        mosk[i].child.push_back(buf);
                        cin >> buf;
                }
        }
        bool stop=false;
        while(stop==false)
        {
                stop=true;
                for (int i=0;i<numb_of_members;i++)
                {
                        for(int j=0;j<mosk[i].child.size();j++)
                        {
                                if (mosk[mosk[i].child[j]].latency <= mosk[i].latency)
                                {mosk[mosk[i].child[j]].latency = mosk[i].latency+1; stop=false;}
                        }
                }
        }
        sort(mosk.begin(),mosk.end(),member_less());
        for (int i=0;i<numb_of_members;i++)
        cout << mosk[i].number << " ";
        return 0;
}

But I have got errors:

685a5f5c-5454-4df3-be25-6c467c9fdfd1
685a5f5c-5454-4df3-be25-6c467c9fdfd1(14): error: binary_function is not a template
  struct member_less : public binary_function<member, member, bool>
                              ^

685a5f5c-5454-4df3-be25-6c467c9fdfd1(14): error: not a class or struct name
  struct member_less : public binary_function<member, member, bool>

Why? On my computer this programm works well!
