About codecard

Time is valuable. Use short blocks of spare time throughout your day to learn data structures and programming by solving coding problems. Whether preparing for a coding interview, trying to learn coding at home, training to improve existing skills, or simply wanting a healthy workout for your brain, CODECARD is a fun way to spend your spare time wisely.

Each problem is printed on a card designed to be used on mobile devices. The front of the card states the problem. The back of the card contains a live code editor where you can develop, run, and test your code. When your code passes all tests, the card is removed from the deck and your solution is saved to a review menu. Sample solutions with optimal time and space complexity are also available for each problem. For best results complete at least one problem each day and periodically review provided solutions, comparing them to your own attempts.

Enjoy coding everywhere!
