Visualizing different Big … WebHere's the pseudocode for binary search, modified for searching in an array. The inputs are the array, which we call array; the number n of elements in array; and target, the number being searched for. The output is the index in array of target: Let min = 0 and max = n-1.

WebIf I'm not mistaken, the first paragraph is a bit misleading. Before, we used big-Theta notation to describe the worst case running time of binary search, which is Θ(lg n). The best case running time is a completely different matter, and it is Θ(1). That is, there are (at least) three different types of running times that we generally consider: best case, … WebBinary Search - Given an array of integers nums which is sorted in ascending order, and an integer target, write a function to search target in nums. If target exists, then return its index. Otherwise, return -1. You must write an algorithm with O(log n) runtime complexity. Input: nums = [-1,0,3,5,9,12], target = 9 Output: 4
