WebAn element is called a peak element if its value is not smaller than the value of its adjacent elements (if they exists). Given an array arr [] of size N, Return the index of any one of its peak elements. Note: The generated output will always be 1 if the index that you return is correct. Otherwise output will be 0. Example 1: WebJan 1, 2024 · Peak Index (Bitonic Point) : A Bitonic Point is a point in bitonic sequence before which elements are strictly increasing and after which elements are strictly decreasing So in this que. we have to find that peak-index (bitonic point) or you can say max value in array. Approach Linear Search Code
WebIn other words, both will meet at the only peak point in mountain array. Otherwise, if there is no valid mountain, their first peak point will be different. (Think!) We initialise two variables left and right to climb from opposite ends i.e. left = 0, right = n - 1 Now using loop, we start climbing from the left end and reach the peak.
