Flashcards
0/6
Skip List
Contains multiple levels, skipping over nodes; probabilistic data structure; offers improved average search complexities similar to balanced trees.
Multilevel Doubly Linked List
Nodes can have child pointers to another doubly linked list; facilitates a multilevel, hierarchical structure; used in filesystems for directory hierarchies.
Singly Linked List
Consists of nodes with each node having a single pointer to the next node; used for simple, non-iterative data structures; efficient for stack implementations.
Circular Linked List
The last node points to the head of the list, forming a circle; facilitates repeated cycling through the list; useful in round-robin scheduling.
Unrolled Linked List
Stores multiple elements in each node to reduce overhead; improves cache performance by storing an array of data in each node; beneficial for memory management in large lists.
Doubly Linked List
Nodes have two pointers, to the next and previous node; allows bidirectional traversal; used in more complex applications like browser history.
