Binary search with algorithm
WebJan 11, 2024 · The binary search algorithm works on the principle of divide and conquer and it is considered the best searching algorithm because it's faster to run. Now let's take a sorted array as an example and try to understand how it works: arr = [2, 12, 15, 17, 27, 29, 45] Suppose the target element to be searched is 17. Approach for Binary Search WebBinary 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.
