UCS1312-Data-Structures-LabWork

Programs and complete ADTs for common data structures implemented in C for the coursework on UCS1312: Data Structures course.

Standalone Implementations

Single script, pluggable implementations are available for the following:

Algorithms & Problems

• Dijkstra's Shortest Path (in Python)
• Floyd-Warshal Shortest Path (in Python)
• The Josephus Problem
• Polynomial Representation and Operation using Linked List
• Sorts and Searches

Data Structures

• Stack (with Array)
• Queue (with Array)
• Doubly Linked List
• Circular Linked List
• Binary Search Tree (BST)
• AVL Tree
• Graphs (Adjacency List)
• Graphs (Adjacency Matrix)
• Priority Queue

Complete Abstract Data Types

An ADT implementation involves three components:

1. The data structure (defined in .h files)
2. An interfacing implementation with functions to store & retreive data (defined as ..Impl.c files)
3. The abstract application level, that use the interfacing implementation (defined as ..Appl.c files)

A structured ADT implementations for the following data structures are included.

• Array-based List
  • Application: Numeric list with search and sort techniques applied: Linear & Binary Search, Shell & Selection Sort
• Singly Linked List
  • Application: Simple student database without sorting
• Linked List -based Stacks
  • Application: Interconversion between Infix and Postfix Expressions
• Doubly Linked List -based Circular Queue
  • Application: CPU Scheduling Queue
• Binary Trees
  • Application: Interconversion between Infix and Postfix Expressions
  • Application: Players database with in-order, post-order and pre-order traversal
• AVL Trees
  • Application: Dictionary of words with sorted insertion and search
• Graph using Adjacency Lists
  • Algorithm Application: Dijkstra's Shortest Path
  • Algorithm Application: Depth-first Search
• Hash Table binned with Linked Lists
  • Application: Simple integer search
• Priority Queue
  • Application: Employee database index by employee ID
