WebFeb 25, 2024 · Binary Search is a searching algorithm used in a sorted array by repeatedly dividing the search interval in half. The idea of binary search is to use the information that the array is sorted and reduce the … 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.
WebA binary search is a much more efficient algorithm than a linear search. In an ordered list of every number from 0 to 100, a linear search would take 99 steps to find the value 99. A binary...
