I have an interview scheduled in a week or so. Normally I generally decline interviews if they are the DS and Algorithms type (for a variety of reasons, none of which I wish to go into here). As such my 'leetcode game' is pretty week. However I now have a pretty interesting opportunity, which unfortunately necessitates a leetcode style interview.
Is there a good refresher course on Youtube/Udemy/any other site, which could quickly get me back to the point where I can start working on leetcode problems?
I'm primarily interested in the DS like trees and graphs, and algorithms surrounding them, since this is something I've never really paid much attention to.
