Count Odd Numbers in an Interval Range - LeetCode

어거지로 풀긴 했는데, 좀 더 엘레강스한 소스 구성이었으면 좋았을 것 같다.

class Solution:
    def countOdds(self, low: int, high: int) -> int:
        flag = 0
        if low % 2 == 0:
            low -= 1
        else:
            flag = 1
        if high % 2 == 0:
            high -= 1
        return ((high+1)//2 - (low+1)//2) + flag
