The aim of this write-up is NOT to replace roadmaps or other guides available out there. I was getting many messages asking about similar things and it was a mess to reply to each and every one. That is why I thought of compiling everything and present in a better format.

Computer Science Fundamentals

It does not matter if you are a university graduate, BootCamp student, or self-taught developer you should know the following subjects in order to build a fine base for your software engineering journey.

  Which language to use for LeetCode/practice and why?

  I will mention my favorite (no clickbait) perspectives from which you can develop your own:
• Pirate King
• Clément Mihailescu
• NeetCode

  Secret Weapon for Problem Solving

  There is no such thing :)

1. Start by learning basic DSA
2. Solve the 100 most liked list from LeetCode
3. Start solving topic-wise and level-wise questions
4. Once you feel like you have leveled up (you will know it), solve LeetCode cards
5. Take notes about what DS/Algo is useful for a particular situation and notice patterns, do not spend too much time taking notes

• Try multiple solutions for each problem and use the discuss section
• Refer to NeetCode, Kevin Naughton Jr., Nick White

Some advice to keep in mind

Thanks for reading, the next resource article would be related to development ONLY. If I missed any good resources then hit me up on Twitter. I cannot mention everything in one article so these are the ones I have personally studied from. There is a lot of reading material like notes and documentation which I will not share. That is for you to figure out.
