class Solution:
    def intToRoman(self, num: int) -> str:
        number = [1, 4, 5, 9, 10, 40, 50, 90, 100, 400, 500, 900, 1000]
        symbol = ["I", "IV", "V", "IX", "X", "XL", "L", "XC", "C", "CD", "D", "CM", "M"]
        answer = ''
        count_symbol = len(symbol) - 1
        while num:
            count = num // number[count_symbol]
            num %= number[count_symbol]
            while count:
                answer += symbol[count_symbol]
                count -= 1
            count_symbol -= 1
        
        return answer
