In what ways is a binary tree similar to a linked list?

Some similarities between binary trees and linked lists include: 1. Structure: Both are made up of nodes containing data and pointers to their respective children or next nodes. 2. Dynamic Data Structures: Their sizes can be altered during the execution of a program by inserting or removing nodes. 3. Recursive Nature: Both can be recursively defined, with binary trees consisting of a node and two smaller binary trees, and linked lists consisting of a node and a smaller linked list. 4. Memory Allocation: Neither requires contiguous memory allocation, allowing for reduced memory usage and fragmentation. 5. Traversal: Both involve following pointers to visit nodes, whether it be with inorder, preorder, and postorder traversals in binary trees or following the next pointers in linked lists.
