Persistent data refers to information that is infrequently accessed and not likely to be modified. This type of data is intended to be permanent and remains unchanged over time. Examples include records in a database that do not change frequently1.
Persistent Data Structures
Persistent data structures are designed to preserve their previous versions when modified. They can be categorized into three types:
Partially Persistent: All versions can be accessed, but only the newest version can be modified.
Fully Persistent: Every version can be both accessed and modified.
Confluently Persistent: Multiple versions can be merged to create a new version, forming a Directed Acyclic Graph (DAG) on the version graph2.
Examples
Linked List Concatenation
Consider concatenating two singly linked lists while preserving the original lists. One way is to copy every node and make the connections, but a more efficient way is to traverse and copy only one of the lists.
