A Python binary search finds the position of an item in a sorted array. It divides a list in half. If a specified value is higher than the middle number, the search focuses on the right of the list. Otherwise, the search looks for the number on the left of the list.

WebThe idea is to use binary search which is a Divide and Conquer algorithm. Like all divide-and-conquer algorithms, binary search first divides a large array into two smaller subarrays and then recursively (or iteratively) operate the subarrays. But instead of working on both subarrays, it discards one subarray and continues on the second subarray. hover compact 330WebJun 3, 2024 · Binary Search is an incredible algorithm to use on large, sorted arrays, or whenever we plan to search for elements repeatedly in a single array.
