📌 First Steps to Begin with DSA
1. Learn a Programming Language
Before diving into DSA, ensure you are comfortable with a programming language. The most recommended languages are:
- C++ (Preferred for competitive programming)
- Java (Widely used in industry)
- Python (Beginner-friendly with easy syntax)
2. Understand Time & Space Complexity
- Learn about Big-O Notation to analyze code efficiency.
- Focus on different complexities: O(1), O(n), O(log n), O(n²), etc.
NOW READ CAREFULLY!!!
Here in the next step, beginners usually confused what to do next? So they start with basic level DSA Topics like Arrays, Strings, etc.. But, here is the tricky thing. Before going further you need to practice a lot of questions of whatever you’ve done till now.
So, once you understand specific language of your choice, time & space complexity. Now you need to practice at least 25-30 pattern questions.
3. Pattern Problems
As you read in above lines about pattern questions. We’ve prepare a document for you to get started with pattern problems. We’ve divided patterns into basic & advanced level so do it accordingly.
