As you all know, I struggle with Maths a bit and sometimes after contests I tend to be “keen on” or very interested in learning a new specific data structure!!
I have found this website thanks to Codechef for Schools (along with some extra digging) which is called:
which, as you can see from the link has ALL problems organized under specific categories like, DP, Trees, etc.
It’s a bit like tags but at same time is also more visual and it actually allows one to see how many problems from each category you have solved!
So, I thought that maybe some beginners would find this website helpful and I decided to share it here
