How should to be good in Data structures concepts.

Question

I'm feeling tough enough to understand linked list concepts.

Answer 1

The best way to be good in data structures is to take the time to figure out why they are how they are. I can throw together code for most common ones in a few minutes without any bugs because I understand them completely. If you can't understand something after an hour of trying, then asking for an explanation makes sense. But, figuring it out yourself helps you maintain the information.
