题目只能简单考虑,测试用例中有得签离时间小于签到时间,按理说上应该是跨了一天的,但本题不能考虑这种情况
#include <iostream> #include "map" using namespace std; int main() { int n; while (cin >> n) { // 注意 while 处理多个 case // cout << a + b << endl; map<string, string> inMap; map<string, string> outMap; while (n--) { string name; string inTime; string outTime; cin >> name >> inTime >> outTime; inMap[inTime] = name; outMap[outTime] = name; } cout << inMap.begin()->second << ' '; auto it = outMap.end(); it--; cout << it->second << endl; } } // 64 位输出请用 printf("%lld")
