WebBinary search is a search algorithm that finds the position of a target value within a sorted collection of data (we are taking array here). It is a fast search algorithm with run-time complexity of Ο (log n). It works on the principle of divide and conquer. WebApr 10, 2024 · Binary search is an algorithm used to find an element i.e., key in a sorted array. Binary algorithm works as below − Let us say that array is ‘arr’. Sort the array in ascending or descending order. Initialize low = 0 and high = n-1 (n = number of elements) and calculate middle as middle = low + (high-low)/2.
