Description
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 Explanation: The odd numbers between 8 and 10 are [9].
Constraints:
0 <= low <= high <= 10^9
Solution
Python3
class Solution:
def countOdds(self, low: int, high: int) -> int:
return (high - low) // 2 + int(low & 1 or high & 1)
