+Problem Statement:
+1523. Count Odd Numbers in an Interval Range
+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].
