Given an integer array `arr`, return `true` if there are three consecutive odd numbers in the array. Otherwise, return `false`.

Example 1:

    Input: arr = [2,6,4,1]
    Output: false
    Explanation: There are no three consecutive odds.

Example 2:

    Input: arr = [1,2,34,3,4,5,7,23,12]
    Output: true
    Explanation: [5,7,23] are three consecutive odds.

Constraints:

- `1 <= arr.length <= 1000`
- `1 <= arr[i] <= 1000`
