WebFeb 12, 2009 · Binary search can be used to access ordered data quickly when memory space is tight. Suppose you want to store a set of 100.000 32-bit integers in a searchable, ordered data structure but you are not going to change the set often. 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. Scope. This article is about sorting the list using the binary search algorithm. Takeaways
