Questions & Step-by-Step Solutions

What is a real-world application of binary search trees?
  • Step 1: Understand what a binary search tree (BST) is. It is a data structure that stores data in a sorted manner.
  • Step 2: Learn that in a BST, each node has a value, and the left child has a smaller value while the right child has a larger value.
  • Step 3: Recognize that BSTs allow for quick searching of values because you can skip half of the tree at each step.
  • Step 4: Identify a real-world application, such as a phone book, where names are stored in alphabetical order.
  • Step 5: Realize that when you want to find a name, you can use a BST to quickly locate it without checking every name one by one.
  • Step 6: Note that BSTs also allow for easy addition of new names and removal of existing names while keeping the list sorted.
