In binary search algorithm, we take the middle element of the array. And search the required element at this position. There are three cases that arise on comparing the middle element of the array with the searchElement. Case 1:If (middle element == searchElement), return the index of the...

In computer science, binary search is a search algorithm that finds the position of a target value within a sorted array. 二分搜索算法 在对数组的搜索算法之中,最朴素的思想就是从数组的第一个元素开始,逐个将数组中的元素与目标值做比较,以得到用户期望的元素下标,因此朴素的搜索算法是一种O(N)时间...
Binary Search is a searching algorithm for finding an element's position in a sorted array. In this tutorial, you will understand the working of binary search with working code in C, C++, Java, and Python.

When we put those numbers in a binary search tree, we only need average(1 + 2 + 2 + 3 + 3 + 3 + 3) / 7 = 2.42 comparisons to find the number. The Binary Search Tree 's search algorithm is roughly O(log2n) However this is the best-case . ...
