Given two non-negative integers low and high. Return the count of odd numbers between low and high (inclusive).
Example 1:
Input: low = 3, high = 7
Output: 3
Explanation: The odd numbers between 3 and 7 are [3,5,7].
Example 2:
Input: low = 8, high = 10
Output: 1

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