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. WebApr 16, 2024 · Are the arrays sorted? If so, I'd recommend a third way: Create a little meta array containing only the bounds of the arrays. On this array you conduct a binary search to find the array your value is in. Then proceed with 'normal' binary search on the found array. – Michael Hoff Apr 16, 2024 at 14:15 1
