Given an integer, convert it to a roman numeral.

Input is guaranteed to be within the range from 1 to 3999.

 

class Solution {
public:
    string intToRoman(int num) {
        int values[] = {1000, 900, 500, 400, 100, 90, 50, 40, 10, 9, 5, 4, 1 }; //数组的初始化
        string numerals[] = {"M", "CM", "D", "CD", "C", "XC", "L", "XL", "X", "IX", "V", "IV", "I" };
        int size = sizeof(values) / sizeof(values[0]); //获取数组的大小
        string result = "";

        for (int i = 0; i < size; i++) {
            while (num >= values[i]) {
                num -= values[i];
                result+=numerals[i];
            }
        }
        return result;
    }
};
