I am preparing for coding rounds that would be conducted for hiring interns. I have solved very few LC hard problems, since I am in short of time, I would like to get a list of good/ important LC hard problems. I hope providing such a list would be helpful not only for me but also for those who would want it in the future.
Any links to the LC posts, that have such lists would be helpful! If you do not have any lists, but do know few problems that are really good - please do share them! BTW would constantly practising medium level LC problems and being good with them be enough to crack the interviews or do we need to solve the hard problems too?
