A Note on Decoded and Patterns

While learning programming, it's easy to focus on solutions without fully understanding the logic behind them.

To make learning a bit clearer, I built two small apps:

1. Decoded — to understand how DSA problems are solved
2. Patterns — to understand how pattern problems work

Both focus on explaining the approach, rather than just showing code.

Decoded

Decoded helps learners understand commonly asked DSA problems visually.

Instead of only showing code, the platform explains how an algorithm works step by step.

Some of the things it includes:

• Animated dry run of the algorithm with user input
• Time and space complexity explanations
• Follow-up questions to explore the problem more deeply
• Explanations of data structures, their operations, and complexities
• Common problem patterns like two pointers, sliding window, etc.
• Tips on recognizing patterns and avoiding common mistakes

The goal is to help learners understand what the problem is asking and how to approach it.

Patterns

https://patterns-azure.vercel.app/

Pattern problems are some of the first exercises we encounter while learning programming.

The Patterns app shows different types of patterns such as:

• Star patterns
• Number patterns
• Alphabet patterns
• and more

Each pattern includes:

• the pattern itself
• the logic behind it
• a JavaScript implementation

Understanding these problems helps beginners learn how loops and conditions work together.

Both apps focus on one simple idea:

Programming becomes easier when you understand the logic, not just the code.
