1630 Count Odd Numbers In An Interval Range

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].

 

Constraints:

0 <= low <= high <= 10^9

impl Solution {
    pub fn count_odds(low: i32, high: i32) -> i32 {
        if low % 2 == 0 && high % 2 == 0 {
            return (high - low ) / 2;
        }
        
        if low % 2 == 0 || high % 2 == 0 {
            return (high - low ) / 2 + 1;
        }

         if low % 2 != 0 && high % 2 != 0 {
            return (high - low ) / 2 + 1;
        }
        0
    }
