[jobdu]扑克牌顺子

一开始看到题还以为要DFS还是BFS，后来发现完全不用。排个序，然后看看大小王能不能弥补缺口就行，但后来又发现还要排除有相同大小牌的情况。

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

int main() {
    int n;
    while (cin >> n && n != 0) {
        vector<int> cards;
        int kingCount = 0;
        while (n--) {
            int x;
            cin >> x;
            if (x == 0) {
                kingCount++;
            }
            else {
                cards.push_back(x);
            }
        }
        sort(cards.begin(), cards.end());
        bool lucky = true;
        for (int i = 1; i < cards.size(); i++) {
            if (cards[i] == cards[i-1]) {
                lucky = false;
            }
            kingCount -= cards[i] - cards[i-1] - 1;
            if (kingCount < 0) {
                lucky = false;
            }
        }
        if (lucky) {
            cout << "So Lucky!" << endl;
        }
        else {
            cout << "Oh My God!" << endl;
        }
    }
}
