题解 | #I Wanna Be the Guy#

本来是个简单题，结果被我想复杂了，卡了好久（哭；

#include <bits/stdc++.h>

using namespace std;
set<int> a;
int n;    
int j = 1;
void in(int len)
{
    int x;
    for (int i = 0; i < len; i++)
    {
        cin >> x;
        a.insert(x);
    }
}
int main()
{
    cin >> n;

    int p, q;
    cin >> p;
    in(p);
    cin >> q;
    in(q);
    if(a.size() >= n) printf("I become the guy.");
    else printf("Oh, my keyboard!");
    return 0;
}
