Learn Programming and DSA from Scratch

 

How to Use MyCodeSchool Playlists to Learn Programming and DSA from Scratch

If you are an absolute beginner and feel confused about where to start coding, the MyCodeSchool YouTube playlists are one of the best free resources available. They focus on clarity, fundamentals, and visual explanations rather than shortcuts or trends.

Used in the right order, these playlists can take you from basic programming to Data Structures and Algorithms (DSA) and finally to a clear understanding of time and space complexity.

Step 1: Start with Programming Fundamentals

Begin with the C and C++ programming basics playlists on MyCodeSchool. These playlists teach how programs actually work at the memory level, which is extremely important for beginners.

Focus on understanding:

  • Variables and data types

  • Conditional statements and loops

  • Functions and recursion

  • Pointers and memory basics

Do not rush this stage. Even if you plan to code in Java, Python, or JavaScript later, these fundamentals will make learning any language easier. Write code alongside the videos and experiment with small changes.

Step 2: Move to Data Structures

Once you are comfortable writing simple programs, start the Data Structures playlists. This is where MyCodeSchool truly shines.

Follow the natural order:

  • Arrays

  • Linked Lists

  • Stacks and Queues

  • Trees

  • Graphs

Each topic is explained visually, making it easier to understand how data is stored and accessed in memory. Pause the videos, draw diagrams, and implement every data structure yourself after watching.

Step 3: Learn Algorithms Slowly and Clearly

After data structures, move on to Algorithms playlists such as:

  • Searching and sorting algorithms

  • Recursion-based problems

  • Tree and graph algorithms

At this stage, your goal is not speed but understanding. Dry-run algorithms on paper, trace how data moves, and then code them. This habit builds strong problem-solving skills.

Step 4: Understand Time and Space Complexity

Finally, watch the Time Complexity and Big O notation videos in the MyCodeSchool playlists.

Here you will learn:

  • What Big O notation really means

  • How to compare algorithms

  • How data structures affect performance

Revisit the code you wrote earlier and analyze its time and space complexity. This will connect all the concepts you learned and give you interview-level clarity.

How to Use These Playlists Effectively

  • Watch videos actively, not passively

  • Pause and rewatch difficult sections

  • Draw diagrams and dry-run code

  • Implement everything yourself

  • Be patient and consistent

Final Words

The MyCodeSchool playlists are timeless. If followed with discipline, they can take a complete beginner from zero programming knowledge to strong DSA fundamentals.

You do not need to chase multiple resources. One clear path, practiced well, is more powerful than many courses watched halfway.

Happy learning and keep building.
