문제 링크입니다: https://www.acmicpc.net/problem/1550

간단한 진법 변환 문제였습니다.

#include <iostream>

#include <string>

using namespace std;

 

int main(void)

{

        ios_base::sync_with_stdio(0);

        cin.tie(0);

        string s;

        cin >> s;

 

        long long result = 0;

        long long temp = 1;

        for (int i = s.length() - 1; i >= 0; i--)

        {

                 if (s[i] >= '0' && s[i] <= '9')

                         result += (s[i] - '0')*temp;

                 else

                 {

                         switch (s[i])

                         {

                         case 'A':

                                 result += 10 * temp;

                                 break;

                         case 'B':

                                 result += 11 * temp;

                                 break;

                         case 'C':

                                 result += 12 * temp;

                                 break;

                         case 'D':

                                 result += 13 * temp;

                                 break;

                         case 'E':

                                 result += 14 * temp;

                                 break;

                         case 'F':

                                 result += 15 * temp;

                                 break;

                         }

                 }

                 temp *= 16;

        }

        cout << result << "\n";

        return 0;

}
