Detailed explanation-1: -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.
Detailed explanation-2: -There are two forms of binary search implementation: Iterative and Recursive Methods. The most significant difference between the two methods is the Recursive Method has an O(logN) space complexity, while the Iterative Method uses O(1).
Detailed explanation-3: -Short answer: you don’t, it is not its purpose. A binary search only gives you the position of the value you want, or the position of 1 of them if duplicated. To display all duplicates and indexes, you need to do a secondary search around the position returned by binary search routine.
Detailed explanation-4: -Binary Search is a searching algorithm used in a sorted array by repeatedly dividing the search interval in half.
Detailed explanation-5: -Binary search follows the divide and conquer approach in which the list is divided into two halves, and the item is compared with the middle element of the list. If the match is found then, the location of the middle element is returned.
