Sign in to saveAlso known as half-interval search, logarithmic search, binary chop
search algorithm in sorted lists that operates by decreasing the search space by half each pass
AI overview
Binary search is a method for finding a specific item in a sorted list by repeatedly dividing the search area in half, eliminating half of the remaining possibilities with each step. It matters because this approach is much faster than checking every item one by one, especially when dealing with large lists.
