Introduction to Data Structures
- Basic terminology and internal representation of primitive data structures.
- Integers, floating-point numbers, decimals, characters, unions, structures, and pointers.
- Data types: arrays.
Data Types: Arrays
- Definition and memory organization.
- Various array operations:
- Insertion, deletion, traversing, updating, and resizing.
Other Data Structures
- Stacks
- Basic operations, stack, and its applications
- Queues
- Queue operations, circular queue, priority queue, applications
- Linked lists
- Singly linked lists and their memory representation. Operations like searching, insertion, deletion, traversing, inversion, concatenation, copying, comparison, allocation and deallocation. Doubly linked lists and their operations. Circular link lists and multilevel link lists.
- Trees
- Introduction, binary trees and their representation, operations (creation, transformation into binary trees, traversal, searching, insertion, and deletion), types of trees (e.g., complete binary trees, extended binary trees), general trees, AVL trees, threaded trees, and B-trees. Applications (arithmetic expression evaluation, infix-prefix-postfix notation conversion).
- Graphs
- Formal introduction and types of graphs. Representations such as sequential and list structures, adjacency lists, multilinked representations. Graph searches (BFS, DFS).
- Shortest paths, transitive closure, activity networks, topological sorts, and critical paths.
- Algorithms
- Sorting (bubble, selection, quick, radix, bucket sort, heap sort).
- Dictionaries (hashing).
- Searching (linear and binary).
- Character strings and string operations.
CS703: SIMULATION
- Introduction and application of simulation tools (e.g., NS-2, NS-3).
