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. WebAug 2, 2024 · It should be noted that Binary Search only works on sorted arrays.
