////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
// 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.
// ```
