Purpose of a Tree Data Structure?
Purpose of a Tree Data Structure?
To store and organize hierarchical data, representing relationships between elements in a parent-child manner.
What is a 'leaf' in a tree?
What is a 'leaf' in a tree?
A node in a tree that does not have any children. It represents the end of a branch.
Searching Time Complexity in Balanced BST?
Searching Time Complexity in Balanced BST?
O(log n), where n is the number of nodes in the tree. This efficiency is due to the balanced structure allowing for a divide and conquer approach.
Study Notes
Tree Data Structure
- The primary purpose of a tree data structure is to store data in a hierarchical manner, allowing for efficient search, insertion, and deletion operations.
Tree Terminology
- A 'leaf' in a tree data structure refers to a node that has no children, meaning it is an endpoint in the tree.
Binary Search Tree Operations
- The time complexity of searching for an element in a balanced binary search tree is O(log n), making it an efficient data structure for searching.
