3. Project Euler

If you want to step up your Math/Logic/Algorithm game, you can check out Project Euler, it includes a list of mathematical programming problems that will require all your brainpower to solve.

This is a more pragmatic approach for practicing since it only contains the problem in a very basic text form and does not include a built-in code editor.

One of the most widely used coding platforms, HackerRank contains challenges for different domains like Mathematics, DB (SQL) oriented challenges, AI, coding patterns, etc…

You can solve the challenges directly online, and one of the coolest features is that users can use HackerRank to provide and solve company-sponsored coding challenges
