这是一个模拟题，用STL，set集合去保存就好了，注意吃藕群众，一开始没有注意，仔细看题。然后，这种最好不要自己用二维字符数组去模拟，代码会很长，不好维护。
1 #include<bits/stdc++.h> 2 3 using namespace std; 4 5 int main(){ 6 // ios::sync_with_stdio(false); 7 // cout.tie(NULL); 8 9 set<string> hotel_now; 10 char strs[101][101]; 11 set<string> hotel_history; 12 int n, m, k; 13 string name; 14 while (~scanf("%d", &n)) { 15 16 hotel_now.clear(); hotel_history.clear(); 17 int size = 0; 18 19 for (int i = 0; i < n; i++) { 20 scanf("%d", &m); 21 for (int j = 0; j < m; j++) { 22 scanf("%s", strs[j]); 23 name = strs[j]; 24 hotel_now.insert(name); 25 hotel_history.insert(name); 26 } 27 if (hotel_now.size() == size) { 28 for (int j = 0; j < m; j++) { 29 name = strs[j]; 30 hotel_now.erase(name); 31 } 32 } 33 size = hotel_now.size(); 34 } 35 scanf("%d", &k); 36 for (int i = 0; i < k; i++) { 37 scanf("%s", strs[0]); 38 name = strs[0]; 39 if (hotel_now.find(name) != hotel_now.end()) cout << "Lang Li Ge Lang" << endl; 40 else { 41 if (hotel_history.find(name) != hotel_history.end()) cout << "Check Out" << endl; 42 } 43 } 44 } 45 return 0; 46 }
