Write a program to implement Binary Search in Java. In this tutorial, we are going to implement binary search algorithm in Java. Before implementing this algorithm, let’s first understand what is binary search and how it works.
Binary Search is a searching algorithm that finds the value in a sorted array in O(logN) time complexity. In my previous post i discuss how to implement binary search using iterative method. In this post i’ll explain how to implement binary search using recursion.
Binary Search Program, Algorithm & their Time Complexity. In this tutorial, You’ll learn about binary search algorithm, how it’s useful in searching and the time complexity of a binary search.
A Binary Search is used to search an element in a sorted array. Binary search is also known as half-interval search or logarithmic search. It works by comparing a value (value needs to search) to the middle element an array. If a value matches with the middle element then the position is returned otherwise the algorithm repeats if the value is less than or greater than the middle element.
A Binary search algorithm is efficient than the linear search algorithm. The time complexity of binary search is O(log(n)).
