CS Fundamentals: Binary Search
Test your knowledge of binary search — the efficient algorithm for finding a value in a sorted collection by repeatedly halving the search space.
Questions cover the prerequisite that data must be sorted, the algorithm's time complexity, edge cases, and common implementation mistakes.
It's one of the first 'real' algorithms most programmers learn — see how well you actually know it.
