Video Summary :
Approach 1 (Window of 3 Elements):
This method iterates through the array using a sliding window of size 3. At each step, it checks whether the current element and the next two are all odd numbers. If such a triplet is found, it returns true; otherwise, it continues until the end of the array. It's simple and efficient for this specific check.

Approach 2 (Counting Consecutive Odds):
This method maintains a counter to track the number of consecutive odd numbers. It increments the counter for each odd number found, and resets it when an even number is encountered. If the counter reaches 3 at any point, it returns true. This approach is slightly more flexible and generalizable.
