This discussion board is a place to discuss our Daily Challenges and the math and science
related to those challenges. Explanations are more than just a solution — they should
explain the steps and thinking strategies that you used to obtain the solution. Comments
should further the discussion of math and science.
When posting on Brilliant:
Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

Hi Lokesh,
I just wanted to clarify your request. Are you asking for a way to look at old problems that is a little more user-friendly than scrolling through the past solutions? A way to do problems you have already seen as if they were new? E.g. say you solved a problem a long time ago and no longer remember how to do it. Would you like to access it and do it again without seeing the solution immediately?
I was requesting the second one - 'A way to do problems you have already seen (or not) as if they were new'. This might result in two benefits. Firstly if a person wants to do lots of problems or practice, he can do so by accessing previous weeks problems. Secondly if a person needs to solve a problem again which he wasn't able to solve earlier but kept thinking about till he had the solution, he can have another chance to play with it. This is particularly the case with computer science. I am learning Python and sometimes want to access last few weeks problems which I didn't knew to solve back then but know now. So, if you can provide a way to access both seen and unseen last few week problems as if they were new this would be great.
