21355번: Personnummer

간단한 구현 문제였습니다.

 

	#include <iostream>
	#include <string>
	using namespace std;
	int main(void)
	{
	ios_base::sync_with_stdio(0);
	cin.tie(0);
	string socialSecurityNumber;
	cin >> socialSecurityNumber;
	string result;
	if (socialSecurityNumber.find('-') == string::npos)
	{
	if (socialSecurityNumber.substr(0, 2) < "20")
	{
	result = "19" + socialSecurityNumber;
	}
	else
	{
	result = "18" + socialSecurityNumber;
	}
	}
	else
	{
	if (socialSecurityNumber.substr(0, 2) <= "20")
	{
	result = "20" + socialSecurityNumber;
	}
	else
	{
	result = "19" + socialSecurityNumber;
	}
	}
	for (int i = 0; i < result.size(); i++)
	{
	if (result[i] == '+' || result[i] == '-')
	{
	continue;
	}
	cout << result[i];
	}
	cout << "\n";
	return 0;
	}
