In various folders of the above topics, you can find questions and concepts related to that topic.
-
In the Dynamic Programming section, you can find all the questions covered and not covered in Aditya Verma's dynamic programming playlist folder-wise with my handwritten notes.✍️
-
If you are preparing for an interview from Striver’s SDE Sheet then the 30-Days-SDE-Sheet-Practice will be helpful to you. Here I have stored solutions to questions of each day with short notes to each solution, as short notes about the approach are very helpful during revision.🎯
-
In the Questions-Sheet directory, you can find questions asked by top product-based companies.
-
There is a collection of books and pdfs on various important computer science fundamentals in the BOOKS-and-PDFs directory.📚
