# Fundamental Data Structures & Algorithms using C language.

via Udemy

### Overview

Learn Data Structures and algorithms for Stack, Queue, Linked List, Binary Search Tree and Heap ( using C Programming ).

What you'll learn:
• Recursion, Stack, Polish Notations, infix postfix, FIFO, Circular & Double Ended Queue, Linked List - Linear, Double & Circular, Stack & Queue using Linked List
• What is stack, algorithms for Push and Pop operation. Implementation of Stack data structure using C.
• Using Stack - checking parenthesis in an expression
• Using Stack - Understanding Polish notations, algorithm and implementation of infix to postfix conversion and evaluation of postfix expression
• What is a FIFO Queue, understanding Queue operations - Insert and delete, implementing FIFO Queue
• Limitations of FIFO queue, concept of Circular Queue - Implementation of Circular queue.
• Concept of Double ended queue, logic development and implementation of double ended queue.
• Concept of Linked List - definition, why we need linked list.
• Singly Linked List - developing algorithms for various methods and then implementing them using C programming
• Doubly Linked List - developing algorithm of various methods and then implementing them using C programming
• Circular Linked List - developing algorithm of various methods and then implementing them using C programming
• How to estimate time complexity of any algorithm. Big Oh, Big Omega and Big Theta notations.
• Recursion, concept of Tail recursion, Recursion Vs Iteration.
• Binary Tree, definition, traversal (in-order, pre-order and post-order), binary search tree, implementation.
• Heap - concept, definition, almost complete binary tree, insertion into heap, heap adjust, deletion, heapify and heap sort.

This course will help the students ability to grasp the knowledge of data structures and algorithm using the C programming language. Knowledge of Data Structures and Algorithms are essential in developing better programming skills.

This course is based on the standard curriculum of Universities across the globe for graduate level engineering and computer application course.

Apart from step by step development of concepts students will also learn how to write algorithms and then how to write programs based on the algorithms in this course.

You will learn the following in this course: (All implemented using C programming)
