Description

Want to learn algorithms quickly without getting overwhelmed? This 1-hour crash course is designed to give you a clear, practical, and easy-to-follow understanding of core algorithm concepts in the simplest way possible. Whether you are a student, a beginner programmer, or someone who wants to strengthen problem-solving skills, this course will guide you step by step from the basics to essential algorithmic thinking.

In this course, you’ll learn how to analyze algorithms using Big O notation, understand how to measure efficiency, and make better decisions about which algorithm to use in different situations. You will also master a fundamental sorting algorithm (Bubble Sort), learning it step by step with visual explanations, so you can understand exactly how the elements are compared, swapped, and sorted.

Additionally, we will explore recursion and dynamic programming through the classic Rod Cutting problem, showing you both the intuitive recursive approach and the optimized dynamic programming solution. This will give you a strong foundation for tackling other common problems in programming and competitive coding.

The teaching style is visual, interactive, and beginner-friendly, using step-by-step explanations, hand-drawn examples, and simple illustrations so you can follow along easily — even if you have no prior experience in programming or algorithms. Each concept is broken down into manageable pieces to ensure clarity, and practical examples are used to reinforce learning.

By the end of this course, you will have a strong understanding of fundamental algorithms, the ability to analyze efficiency, and the confidence to solve beginner-level algorithmic problems independently. This crash course will also prepare you for more advanced topics, including other sorting algorithms, graph algorithms, and dynamic programming techniques.

If you’re looking for a fast, focused, and easy introduction to algorithms that gives practical skills you can apply immediately, this crash course is the perfect place to start. You’ll save time, avoid confusion, and gain the confidence to tackle algorithm challenges in school, exams, or coding interviews.

Who this course is for:

  • Beginners in computer science or programming who want to learn algorithms step by step.
