Solution: Find Peak Element
Understand how to find a peak element in a 0-indexed integer array by applying a modified binary search technique. Learn to compare middle elements with neighbors, discard half the search space iteratively, and guarantee a peak in logarithmic time. This lesson helps you master a common coding interview pattern essential for efficient problem solving.

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 ...
