Peak index in mountain array
WebFor this problem, we are trying to find a index where a[mid] > a[mid -1] AND a[mid] > a[mid + 1]. That is what the definition of a peak is. We can use binary search to do this in O(log n) time, but before we go on we need to set up some ground rules on what values we will land on, and what do they mean. WebJan 13, 2024 · Find the peak index from the mountain array. Based on the obtained peak index, the partition array into two parts. It searches for its left side first using Binary …

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. 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.
