Solution: Find Peak Element
Explore how to identify a peak element in a 0-indexed integer array by applying a modified binary search technique. This lesson guides you through the process of efficiently narrowing down the search space to find a peak index in O(log n) time, ensuring a clear understanding of the algorithm's steps and its constant space complexity.

Statement
You’re given a 0-indexed integer array nums. An index i is called a peak if nums[i] is strictly greater than its neighboring values (the elements immediately to its left and right, if they exist). Assume the array has virtual boundaries where nums[-1] = nums[n] = -∞, so the first and last elements can also be peaks.
Your task is to return the index of any one peak ...
