# 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
#
