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.
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 WebBinary search is an efficient algorithm for finding an item from a sorted list of items.
