Three Consecutive Odds
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

思路一：遍历

    public boolean threeConsecutiveOdds(int[] arr) {
        int n = 0;

        for (int i : arr) {

            if ((i & 1) == 1) {
                n++;
            } else {
                n = 0;
            }

            if (n >= 3) return true;
        }

        return false;
    }
