amazing portal for coding problems
Found these 2 unique websites to try and practice coding.
Project Euler- Mostly mathematical questions but mind blowing.
Rosalind - Bioinformatics based but helpful for all engineers.
Please share your views and other alternate platforms if aware.
Depends on your goals. Leetcode for grinding problem solving. Geeks for geeks for the basics. For mock interviews, couldn't find good websites.
Shameless plug: I am building a FAANG AI interviewer to practice mock interviews. Will be out soon.
