Binary Search is a fast and efficient way to find an element in a sorted array. In this tutorial, you will learn how binary search works, how to implement it in C, C++, Java, and Python, and how to analyze its time complexity. Whether you are preparing for a coding interview or want to improve your algorithm skills, this tutorial will help you master binary search.
Jun 27, 2024 · Complexity Analysis of Binary Search Algorithm: Time Complexity: Best Case: O(1) Average Case: O(log N) Worst Case: O(log N) Auxiliary Space: O(1), If the recursive call stack is considered then the auxiliary space will be O(logN). Applications of Binary Search Algorithm:

Given a sorted array arr and an integer k, find the position(0-based indexing) at which k is present in the array using binary search. Examples: Input: k = 4, arr= [1 ...
Binary Search Algorithm - Binary search is a fast search algorithm with run-time complexity of Ο(log n). This search algorithm works on the principle of divide and conquer, since it divides the array into half before searching. For this algorithm to work properly, the data collection should be in the sorted form.
Mar 2, 2023 · Binary Search is a searching algorithm used in a sorted array by repeatedly dividing the search interval in half and the correct interval to find is decided based on the searched value and the mid value of the interval.
Nov 29, 2023 · Last update: November 29, 2023 Original Binary search¶. Binary search is a method that allows for quicker search of something by splitting the search interval into two. Its most common application is searching values in sorted arrays, however the splitting idea is crucial in many other typical tasks.
In computer science, binary search, also known as half-interval search, logarithmic search, or binary chop, is a search algorithm that finds the position of a target value within a sorted array. Binary search compares the target value to the middle element of the array. If they are not equal, the half in which the target cannot lie is eliminated and the search continues on the remaining half, again taking the middle element to compare to the target value, and repeating this until the target ...
Binary search is an efficient algorithm for finding an item from a sorted list of items. It works by repeatedly dividing in half the portion of the list that could contain the item, until you've narrowed down the possible locations to just one.
May 2, 2016 · Binary search is an efficient algorithm that searches a sorted list for a desired, or target, element. For example, given a sorted list of test scores, if a teacher wants to determine if anyone in the class scored \(80\), she could perform a binary search on the list to find an answer quickly.
