Hint

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

class Solution {

    /** T : O(n)  S : O(1) */
    public boolean threeConsecutiveOdds(int[] arr) {
        for( int i=0 ; i<= arr.length-3; i++){
            if( arr[i]%2==1 && arr[i+1]%2==1 && arr[i+2]%2==1 ) return true;
        }
        return false;
    }
