It is a just a list containing some hard and/or interesting problems that would be useful to know for interviews. You can use this to track the problems you solve.
White Cell: Means this problem is available, but you haven't attempted yet.
Yellow Cell: Means that you have read the problem statement and are currently trying to solve the problem.
Green Cell: Means that you've solved the problem successfully.
Go to the homepage by clicking on the title. Then, by clicking on a cell (outside the problem links), you can toggle the state of a problem.
It is fully built in HTML, CSS and JavaScript.
The checklist is saved locally, on your brwoser's local storage.
I intend to make the checklist dynamic, allowing people to pick and choose their own questions to include in here.
I also intend to make it such that you can log into the website, and the checklist is tied to your account instead of your local storage.
I hope to also be able to make it such that you can copy a view link for your checklist, and share it with others.
