Study Notes
Linear Data Structures
- A linear list is an example of a linear data structure
- Linear data structures are growable and pseudo-dynamic
- Elements in a linear data structure are arranged in a specific order
- What makes a data structure linear is the way elements are arranged in a specific order
- Linear ADTs are practically effective
- An array is an example of a linear data structure used for organizing computer memory
- A characteristic of a list data structure is that elements are arranged in a specific order
- Elements in a list are arranged in a specific order
LinkedList-Based Implementations
- In LinkedList-based implementations, physical position and logical order are not directly related
- In array-based implementations, physical position and logical order are directly related
- Linear data structures allow access and manipulation of elements at any point
- Arrays are physically ordered, while linked lists are logically ordered
- A disadvantage of physically ordered arrays compared to logically ordered linked lists is the complexity of insertion and deletion operations
List Operations
- There are several types of list operations, including:
- Index-based operations (e.g., retrieving an element at a specific index)
- Iterator-based operations (e.g., adding an element at a specific position)
- Value-based operations (e.g., checking if the list contains a specific element)
- Random access is efficient for array-based implementations
- Linked lists do not support direct/random access
Singly-Linked Lists (SLLs)
- Each node in a singly-linked list contains a reference to the next node
- The head of a singly-linked list contains a reference to the first node
- The tail of a singly-linked list refers to the last node
- Links connect nodes in a singly-linked list
- A key characteristic of singly-linked lists is the absence of direct access
- Linked lists can change their structure by manipulating links
- The size of a singly-linked list changes as nodes are added and removed
- A key consequence of insertion or deletion in a singly-linked list is the need to update links
- A significant advantage of resizing a singly-linked list during insertion or deletion is efficient use of memory
Doubly-Linked Lists (DLLs)
- Each node in a doubly-linked list contains references to both the previous and next nodes
- The header of a doubly-linked list contains references to the first and last nodes
- A key characteristic of doubly-linked lists is the presence of both previous and next references
- The time complexity for adding a new node at the head or tail of a doubly-linked list is O(1)
- The time complexity for adding a new node at an unknown position in a doubly-linked list is O(n)
DLL Node and Header Classes
- Each DLL node contains a reference to the previous and next nodes
- The DLL header contains references to the first and last nodes
- The purpose of the 'prev' attribute in the DLL node class is to reference the previous node
- The purpose of the 'next' attribute in the DLL node class is to reference the next node
- The DLL header typically contains references to the first and last nodes
