1523. Count Odd Numbers in an Interval Range

Leetcode Solutions

Counting Odd Numbers in an Interval Using Mathematical Approach

  1. Check if low is odd using the bitwise AND operator (low & 1). If it is not odd, increment low by 1.
  2. Calculate the number of odd numbers between low and high using the formula (high - low) / 2 + 1.
  3. If low was incremented and became greater than high, return 0, as there are no odd numbers in the range.
  4. Otherwise, return the calculated count.
