WebMay 2, 2016 · Binary search is an efficient algorithm that searches a sorted list for a desired, or target, element. For example, given a sorted list of test scores, if a teacher wants to determine if anyone in the class scored … WebA Binary Search in Python is a technique for finding a specific element in a sorted list. The algorithm operates by recursively splitting sublists until they can be searched to the desired value. When scanning massive arrays, a binary search is much more effective than a linear search. Specifically, the binary search runs at a logarithmic time ...
