Write a program to implement binary search using recursion in c. Given a sorted array, we have to search a element in an array using binary search algorithm.
We have a sorted array and we have to search an element from an array using recursive binary search program in c.
What is binary search?
Binary Search is a searching algorithm that search an element in a sorted array in O(logN) time complexity.
In my previous tutorial, I have discussed Binary search program in c using iterative approach. In this post, I am going to explain how to implement a binary search program in c using recursion.
Write a code to implement binary search program in c. Given a sorted array, we have to write a code to search an element in an array using binary search.
A Binary Search is used to search an element in a sorted array. In binary search, we first calculate the mid position of an array. Then, After that we compare element to be search to the middle element an array. If a value matches with the middle element then the index 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)).
