Detailed Explanation:

🔸 Initialize Pointers:
Start with left at the beginning (index 0) and right at the end (last index) of the array.
🔸 Iterate Until Pointers Meet:
Calculate the middle index mid as (left + right) // 2.
Compare nums[mid] with its neighbors:
If nums[mid] is greater than both nums[mid + 1] and (if mid is not at the boundary) nums[mid - 1], mid is the peak.
If nums[mid] is less than nums[mid + 1], the peak is in the right half. So, set left to mid + 1.
Otherwise, the peak is in the left half. So, set right to mid - 1.
🔸 Return Statement:
When left equals right, the pointers have converged to the peak element's index.
