What you'll learn

  • Understand the fundamental concepts behind core data structures like arrays, stacks, queues, linked lists, and trees.
  • Learn how basic algorithms such as searching, sorting, and recursion work through visual explanations and real-life examples
  • Analyze time and space complexity using Big-O notation to evaluate algorithm efficiency.
  • Build a strong theoretical foundation in data structures and algorithms to support further coding practice and interview prep.

  • Introduction13:03

    After attending a basic lecture on lists in Data Structures and Algorithms (DSA), students will be able to:


    Define what a list is and explain its significance as a linear data structure.


    Distinguish between different types of lists: array-based (static) and linked lists (dynamic).


    Describe and compare the characteristics, advantages, and limitations of arrays and linked lists as implementations of lists.


    Perform basic operations on lists such as insertion, deletion, traversal, and searching for elements.


    Identify appropriate use cases for lists in solving real-world programming problems.


    Select and implement the most suitable form of list (array vs. various forms of linked lists) based on problem requirements.

  • Stack and Queue6:51

    After learning the theory of Stacks, students will be able to:

    Understand the concept of a stack as a linear data structure that follows the Last In, First Out (LIFO) principle.


    Define stack operations such as:


    Push: Adding an element to the top of the stack.


    Pop: Removing the top element from the stack.


    Peek/Top: Accessing the top element without removing it.


    isEmpty: Checking if the stack is empty.

  • Lists Explanation7:00

    After learning the theory of linked lists, students will be able to:

    Understand the concept of dynamic data structures and explain how linked lists differ from static structures like arrays.


    Define and describe the structure of a linked list node (data and pointer/link fields) and how nodes are connected.


    Explain the advantages of linked lists, including dynamic memory use and efficient insertions/deletions.


    Distinguish among types of linked lists: singly linked, doubly linked, and circular linked lists, and discuss their properties and appropriate uses.


    Trace and visualize the organization of linked list elements (using diagrams or by following node connections).

Requirements

  • No prior coding experience required — just curiosity and a basic understanding of logic and problem-solving.
