Study Notes
Data Structure
- Data structures are organized formats for storing, managing, and retrieving data efficiently.
- Common types include arrays, linked lists, stacks, queues, trees, and graphs.
- They facilitate operations like searching, sorting, inserting, and deleting data.
Abstract Data Type (ADT)
- An ADT is a model for a data type where its behavior is defined by a set of operations.
- Key properties of ADTs include encapsulation, where implementation details are hidden, providing a clear interface.
- Examples of ADTs include lists, stacks, queues, and trees, each supporting various operations.
List ADT
- The List ADT is a collection of elements with a defined ordering, allowing duplicates.
- Main operations include insertion, deletion, access, search, and traversal.
- Lists can be implemented in several ways, including arrays and linked lists.
Insertion in Singly Linked List
- A singly linked list consists of nodes, each containing data and a pointer to the next node.
- Insertion can happen at various positions: at the beginning, at the end, or in the middle of the list.
- Inserting at the head involves adjusting the head pointer to a new node pointing to the former first node.
- Inserting at the tail requires traversing to the last node and linking it to the new node.
- Insertion in the middle involves finding the appropriate node and adjusting pointers accordingly.
- Complexity of insertion operations is generally O(1) when adding at the head, while it's O(n) for finding the right position.
