I know this probably was asked before, but what if one just memorizes all solutions to
~300 hard problems or any exercises he/she could not solve?
chances are high, the interview will ask a question(especially if it's hard) that i have seen before. so i won't miss it - i will still know how to solve it..
i know it's kind of cheating - i did not really struggle to solve it, did not spend time with it. But if the interview is very soon and i did not practice many hard problems.. then this might be a "QUICK DIRTY LIFEHACK"?
