Binary search in a nearly sorted array

WebThere is an integer array nums sorted in non-decreasing order (not necessarily with distinct values).. Before being passed to your function, nums is rotated at an unknown pivot index k (0 <= k < nums.length) such that the resulting array is [nums[k], nums[k+1], ..., nums[n-1], nums[0], nums[1], ..., nums[k-1]] (0-indexed).For example, [0,1,2,4,4,4,5,6,6,7] might be … WebA binary search of elements in an array requires that the elements be sorted from smallest to largest.

WebThe key idea is that when binary search makes an incorrect guess, the portion of the array that contains reasonable guesses is reduced by at least half. If the reasonable portion had 32 elements, then an incorrect guess cuts it down to have at most 16. Binary search halves the size of the reasonable portion upon every incorrect guess. WebAug 31, 2024 · If the data is nearly sorted or when the list is small as it has a complexity of O (N2) and if the list is sorted a minimum number of elements will slide over to insert the element at its correct location. This algorithm is stable and it has fast running case when the list is nearly sorted. WebBinary search is a faster algorithm for searching a list if the list's elements are sorted and directly accessible (such as an array). Binary search first checks the middle element of the list. If the search key is found, the algorithm returns the matching location. chefs de cuisine education foundation
