Exception을 정의하는 문제다.

입력받은 username의 길이가 5미만인 경우에 대한 exception을 정의하면 된다.

C++ 풀이

#include <iostream>
#include <string>
#include <sstream>
#include <exception>
using namespace std;

/* Define the exception here */
class BadLengthException {
private:
	int n;
public:
	BadLengthException(int N) {
		n = N;
	}

	int what() {
		return n;
	}
};


bool checkUsername(string username) {
	bool isValid = true;
	int n = username.length();
	if (n < 5) {
		throw BadLengthException(n);
	}
	for (int i = 0; i < n - 1; i++) {
		if (username[i] == 'w' && username[i + 1] == 'w') {
			isValid = false;
		}
	}
	return isValid;
}

int main() {
	int T; cin >> T;
	while (T--) {
		string username;
		cin >> username;
		try {
			bool isValid = checkUsername(username);
			if (isValid) {
				cout << "Valid" << '\n';
			}
			else {
				cout << "Invalid" << '\n';
			}
		}
		catch (BadLengthException e) {
			cout << "Too short: " << e.what() << '\n';
		}
	}
	return 0;
