Storing data in a way that allows efficient access and changes is critical in Computer Science. Binary Search Trees are a fundamental tree-like structure that you'll want in your toolkit!
Suppose the keys 55,63,31,17,22,40 are inserted into a binary tree in that order. Which of the following is the BST that is formed?
Given a binary search tree, we want to write a
search method. This method will look for a node with a specific
key and return that node. Below is an incomplete implementation
The two redboxes indicate missing code. What lines should replace box 1 and box 2 respectively?
Which of the insertion sequences cannot produce the binary search tree below?
