Binary Search Tree

Introduction Finding the min and max elements is one of the simplest algorithms regarding BST (Binary Search Tree). The findMin method loops through the left child nodes and returns the value from the last node. The findMax method does the same but traverses the right child nodes. Code Example - Min func findMin() -> Int? { var min: Int? var curr: BSTNode? = self while curr != nil { min = curr?...

What is a Tree? A Tree is a data structure that has a root and subtrees of children, representing a set of linked nodes. Trees behave similarly to a LinkedList in that they have a collection of nodes starting with a head (root). The main difference is that Trees can have multiple children, whereas a LinkedList, on the other hand, can have only one next child. I’m going to focus on a commonly used type of tree, the Binary Search Tree....
