/*****************************************************************************************************
*
* 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
