A-Level Computer Science – Searching Algorithms Explained (Linear, Binary & Tree) (OCR / AQA) | S12:Ep2

This episode introduces various searching algorithms crucial in computer science for finding specific items within data structures. It begins by outlining linear search, which involves sequentially checking each item until a match is found, and analyzes its time complexity as O(n). The text then moves to binary search, a more efficient method for sorted lists that works by repeatedly halving the search space, resulting in a time complexity of O(log n). Finally, the document briefly describes binary tree search algorithms, highlighting their use in quickly navigating data stored in a tree structure and discussing the impact of unbalanced trees on search time.
