Answer from AI
The main types of trees in data structures differ in their structure and purpose:
-
Binary Tree — each node has at most two children (left and right). Used for simple hierarchies and basic operations.
-
Binary Search Tree (BST) — a binary tree where for each node, all values in the left subtree are less, and in the right subtree are greater than the node's value. Allows efficient search, insertion, and deletion of elements.
-
Balanced Trees (e.g., AVL, Red-Black) — variants of BST that maintain balance to ensure logarithmic time operations.
-
General Tree (N-ary Tree) — nodes can have an arbitrary number of children. Used to represent more complex hierarchies, such as file systems.
-
Segment Tree, Fenwick Tree — specialized trees for fast range queries on arrays.
Each type of tree is chosen depending on the operation requirements and data structure.
