Asked By CleverCoder99 On

Hey everyone! I'm diving into competitive programming (CP) while also preparing for coding interviews at top tech companies. I'm just a student with some basics under my belt and I want to:

1. Improve my problem-solving skills and algorithms (DSA).
2. Ace interviews at product-based companies.
3. Follow a consistent roadmap for my learning.

I have a few questions:

- Which programming language is best to start with (C++, Python, Java)?
- What's the best way to practice DSA and CP consistently?
- Are there any recommended YouTube channels, courses, or websites?

LeetCode is crucial for practicing coding problems. You can find solid explanations on YouTube or use Miyagi Labs for interactive learning experiences! Just dive in and keep coding!

For programming language choice, it really depends on your future plans. As for practicing DSA and CP, the key is consistent practice. Make sure to read some guides when starting out with your chosen language!

For competitive programming and interview prep, I highly recommend checking out 'Competitive Programming 4' by Steven Halim et al. It's a great resource that covers data structures, algorithms, and provides loads of practice problems from sites like UVA Online Judge and Kattis. It’s perfect for building a solid foundation, and the beginner sections will help you ease into it. Good luck, and happy coding!

C++ is the most popular for competitive programming due to its speed and Standard Template Library (STL) features, but if you're more comfortable with Python or Java, go for it! Balance your time between doing one CP contest a week on platforms like Codeforces to enhance your speed and practicing DSA problems on sites like LeetCode and InterviewBit. Focus on one topic each week, like arrays or dynamic programming, and solve a few problems daily.

Awesome goals! If you’re looking at web development too, learning TypeScript is super beneficial since it’s widely used in both frontend and backend. Start solving about 1-2 problems a day, focus on understanding patterns, and revisit tough problems later. I found explaining problems out loud really helps cement concepts; it’s how I started creating helpful visual breakdowns for LeetCode problems on my channel! Let me know if you want the link!
