What is a binary search and how is it used in computer science?
A binary search is a method used in computer science to efficiently find a target value within a sorted array or list. It works by repeatedly dividing the search interval in half until the target value is found or determined to be not in the array. This approach is faster than linear search for large datasets because it eliminates half of the remaining elements at each step.
