WebOct 31, 2024 · In its simplest form, binary search is used to quickly find a value in a sorted sequence (consider a sequence an ordinary array for now). We’ll call the sought value the target value for clarity. Binary search maintains a contiguous subsequence of the starting sequence where the target value is surely located. This is called the search space. In computer science, binary search, also known as half-interval search, logarithmic search, or binary chop, is a search algorithm that finds the position of a target value within a sorted array. Binary search compares the target value to the middle element of the array. If they are not equal, the half in which the target cannot lie is eliminated and the search continues on the remaining half, again … WebAug 23, 2024 · The Arrays.binarySearch () method takes the array you want to search as the first argument and the key you're looking for as the second argument.
