Q3. Consider the Movie Recommendation code and problem that was discussed during the class (Session 5 and 6). Please provide a brief write-up on the problem, steps needed to arrive at the solution (recommendation system), and how exactly those steps are implemented in the code. You can make use of the PPT file that discusses the broad solution. While you are doing so, please also mention what each line of code does (It is not sufficient to mention what each block of code does, you would have to provide explanation for each line). (25 Marks)
