inputstandard input
outputstandard output
There is a game called “I Wanna Be the Guy”, consisting of n levels. Little X and his friend Little Y are addicted to the game. Each of them wants to pass the whole game.
Little X can pass only p levels of the game. And Little Y can pass only q levels of the game. You are given the indices of levels Little X can pass and the indices of levels Little Y can pass. Will Little X and Little Y pass the whole game, if they cooperate each other?
Input
The first line contains a single integer n (1?≤??n?≤?100).
The next line contains an integer p (0?≤?p?≤?n) at first, then follows p distinct integers a1,?a2,?…,?ap (1?≤?ai?≤?n). These integers denote the indices of levels Little X can pass. The next line contains the levels Little Y can pass in the same format. It’s assumed that levels are numbered from 1 to n.
Output
If they can pass all the levels, print “I become the guy.”. If it’s impossible, print “Oh, my keyboard!” (without the quotes).
Examples
input
4
3 1 2 3
2 2 4
output
I become the guy.
input
4
3 1 2 3
2 2 3
output
Oh, my keyboard!
Note
In the first sample, Little X can pass levels [1 2 3], and Little Y can pass level [2 4], so they can pass all the levels both.
In the second sample, no one can pass level 4.

题意:如果两个人会的所有level
包括了题目中要求的所有level
,那就输出I become the guy.
,否则输出Oh, my keyboard!
AC代码
#include <iostream>
#include <set>using namespace std;set <int> s;int main()
{
int n;cin >> n;int p;cin >> p;for (int i = 0; i < p; i ++ ){
int a;cin >> a;s.insert(a);}int q;cin >> q;for (int i = 0; i < q; i ++ ){
int a;cin >> a;s.insert(a);}if (s.size() == n)puts("I become the guy.");else puts("Oh, my keyboard!");return 0;
