LeetCode Problem - 1523
class Solution {
// Method to count the odd numbers between 'low' and 'high' (inclusive)
public int countOdds(int low, int high) {
// The formula calculates the count of odd numbers in the range.
// (high + 1) / 2 gives the total number of odd numbers from 1 to high.
// low / 2 gives the number of even numbers up to low, hence subtracting it gives the odd count between low and high.
return (high + 1) / 2 - low / 2;
}
}
