WebBinary Search is a searching algorithm for finding an element's position in a sorted array. In this approach, the element is always searched in the middle of a portion of an array. … WebAn array element is peak if it is NOT smaller than its neighbors. For corner elements,consider only one neighbor. For example: For input array {10, 20, 15, 2, 23, 90, 67} there are two peak elements: 20 and 90. I need to return any one peak element. The solution i tried is a linear scan of array and i found a peak element.

WebMay 4, 2024 · The peak element is an element that is greater than its neighbors. Suppose we have an input array nums, where nums [i] ≠ nums [i+1], search for a peak element and return its index. The array can hold multiple peak elements, in that case return the index to any one of the peak elements. We can imagine that nums [-1] = nums [n] = -∞.
