Tags on practice problems


Can I search practice problems which can be solved using a trie?? I mean, are there any tags to filter the practice problems??

In other words, after reading a particular slice of algos, say on trees (Binary, Heap, AVL etc.), is there any way i can find related practice problems to solve?



Yes, I agree the problems should be tagged. This way better practice can be done.

Yes, i totally agree with you. But, at present there are no options like that. But, there is another site codeforces where you can search problems by tags.
