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 … WebUse the bisect module to do a binary search in Python Implement a binary search in Python both recursively and iteratively Recognize and fix defects in a binary search Python implementation Analyze the time-space …
