About this video AQA Specification Reference A Level 4.3.4.2 An alternative to a linear search, the binary search starts in the middle of a list and removes half of the items from the list until the item you are looking for is found. It is usually more efficient than a linear search. This video introduces the algorithm. Key questions - Can you successfully implement a binary search in a high

The binary search algorithm is a fundamental and highly efficient search algorithm used to find the position of a target value within a sorted array. In Python, implementing this algorithm can significantly improve the performance of search operations, especially when dealing with large datasets. This blog post will explore the binary search algorithm in Python, covering its basic concepts

Implementing Binary Search in Python To implement the Binary Search algorithm we need An array with values to search through. A target value to search for. A loop that runs as long as left index is less than, or equal to, the right index. An if-statement that compares the middle value with the target value, and returns the index if the target value is found. An if-statement that checks if the

Binary Search Algorithm 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 time complexity to O log N. Below is the step-by-step algorithm for Binary Search Divide the search space into two halves by finding the middle index quotmidquot. Compare the

An alternative to a linear search, the binary search starts in the middle of a list and removes half of the items from the list until the item you are looking for is found.

This search is called a binary search because we split the list in two each time. It is usually much faster than a linear search see below Pseudocode for a binary search Python code for the same binary search. three variables are used to remember the positions of the midpoint, a point on the left and a point on the right.
