Binary search in unsorted array
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 … WebApr 23, 2016 · 5. Yes, there is easy way to construct a balanced Binary Search Tree from array of integers in O (nlogn). Algorithms is as follows: Sort the array of integers. This takes O (nlog (n)) time. Construct a BST from sorted array in O (n) time. Just keep making the middle element of array as root and perform this operation recursively on left+right ...
