用了string，如果不用會麻煩很多。

#include <iostream>#include <string>using namespace std;int main(){int t;cin >> t;while(t--){int n;cin >> n;string id, start, end;cin >> id >> start >> end;string idstart, idend, startmin, endmax;idstart = id;idend = id;startmin = start;endmax = end;for(int i = 1; i < n; i++){cin >> id >> start >> end;if(start < startmin){startmin = start;idstart = id;}if(end > endmax){endmax = end;idend = id;}}cout << idstart << " " << idend << endl;}return 0;}
