[Leetcode/C++] 168. Excel Sheet Column Title


class Solution {
public:
    string convertToTitle(int n) {
        string answer = "";
        while(n != 0) {
            answer = (char)((n - 1) % 26 + 'A') + answer;
            n = (n-1) / 26;
        }
        return answer;
    }
};

그냥 단순한 사칙연산과 구현문제였는데 26으로 나누고 마드하는 전형적인 문제이다.
