给你一个整数数组 arr，请你判断数组中是否存在连续三个元素都是奇数的情况：如果存在，请返回 true ；否则，返回 false 。

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

示例 1：

输入：arr = [2,6,4,1]
输出：false
解释：不存在连续三个元素都是奇数的情况。

Example 1:

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

示例 2：

输入：arr = [1,2,34,3,4,5,7,23,12]
输出：true
解释：存在连续三个元素都是奇数的情况，即 [5,7,23] 。

Example 2:

Input: arr = [1,2,34,3,4,5,7,23,12]
