Study Notes

Data Structures

Data structure organizes and stores data in a specific format for efficient access and modification.
Key components include keys (identifiers) and values (content).
Types of data structures:
- Linear: Elements accessed sequentially; may be stored unsystematically.
- Non-Linear: Elements accessed in a non-sequential manner.
Common abstract data types (ADTs) include linked lists, stacks, queues, trees, and sets.

Abstract Data Types (ADT)

ADTs define data views and allowed operations independently from implementation.
Benefits of ADTs:
- Enables changes to implementations without affecting programs using them.
- Facilitates code understanding and maintenance.
Two parts of an ADT:
- Public/External: Data and operations accessible outside.
- Private/Internal: Actual implementation details.

Characteristics of Algorithms

Algorithms are step-by-step instructions for problem-solving.
Essential characteristics:
- Finiteness: Must terminate after a defined number of operations.
- Definiteness: Each instruction should be clear and specific.
- Input: Can have zero or more well-defined inputs.
- Output: Must produce one or more results related to the input.
- Uniqueness: Each step's complexity depends on input and previous steps.

Elements of Algorithms

Components include:
- Sequential operations
- Conditions and actions based on data structure states
- Iteration: Performing a task multiple times.
- Recursion: Function self-calling to solve problems.

Algorithm Design Paradigms

Divide and Conquer: Breaks problems into smaller subproblems, solves them independently.
Greedy Algorithms: Selects the optimal option at each step to find a solution.
Dynamic Programming: Solves overlapping subproblems by reusing results for efficiency.

Data Structure Examples

Linked List: Stores elements as separate objects for dynamic size.
Stack: Operates on a Last-In, First-Out (LIFO) basis.
Queue: Operates on a First-In, First-Out (FIFO) basis.
Tree: Hierarchical arrangement of nodes.
Priority Queue: Processes elements based on priority order.
Heap: A complete binary tree structure with parent-child value relationships.
Set: Collection of unique elements without duplicates.
