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` | ||
