Use a BST (Binary Search Tree) when you require sorted data and efficient lookup, insertion, and deletion operations. BSTs provide average-case O(log n) time complexity for these operations, making them ideal for applications like databases, file systems, and dynamic sets where data changes frequently and needs to be accessed quickly.

FAQs & Answers

  1. What is a Binary Search Tree? A Binary Search Tree (BST) is a data structure that maintains sorted data for efficient insertion, deletion, and lookup operations.
  2. What are the advantages of using a BST? BSTs offer average O(log n) time complexity for key operations, making them useful for applications requiring quick access and frequent data changes.
  3. Where are BSTs commonly used? BSTs are commonly used in databases, file systems, and dynamic data sets that require fast searching and sorting capabilities.
  4. How do Binary Search Trees compare to other data structures? BSTs provide efficient average-case performance for sorted data compared to other structures, but can degenerate into a linked list in the worst case without balancing.
