Syllabus

Bubble Sort Algorithm

In this module, we will cover the bubble sort algorithm, a simple yet inefficient sorting method. You will learn how it repeatedly swaps adjacent elements to sort an array and understand its time complexity, allowing you to evaluate its efficiency in different scenarios.

Selection Sort Algorithm

In this module, we will explore the selection sort algorithm, which sorts an array by repeatedly selecting the smallest or largest element and swapping it into the correct position. You'll gain insights into its time complexity and when to use it for sorting tasks.

Insertion Sort Algorithm

In this module, we will introduce the insertion sort algorithm, which builds a sorted array by inserting each new element into its correct position one by one. You'll learn about its use cases and how it compares to other sorting methods in terms of performance.

Cycle Sort Algorithm

In this module, we will explore cycle sort, an optimal algorithm for minimizing the number of writes. We will also solve several practical problems, including finding missing or duplicate numbers in arrays, using cycle sort techniques to enhance performance and accuracy.

Solving Pattern Questions

In this module, we will focus on solving pattern-based questions, which are common in coding interviews and competitive programming. You will learn how to apply loops and logical thinking to generate different types of patterns and solve related problems efficiently.

Time and Space Complexity

In this module, we will delve into time and space complexity, essential concepts for evaluating the efficiency of algorithms. You will learn to use notations like Big O, Omega, and Theta to measure algorithm performance and how to determine both time and space complexity for practical problems.

Maths for Data Structures and Algorithms

In this module, we will explore key mathematical concepts and algorithms that are fundamental to data structures and algorithms. Topics include prime numbers, the Sieve of Eratosthenes, efficient square root calculations, the Newton-Raphson method, and factorization algorithms, all of which are integral to solving complex computational problems.
