You have collected reviews from four movie reviewers where the reviewers are numbered 0–3. Each reviewer has rated six movies where the movies are numbered 100–105. The ratings range from 1 (terrible) to 5 (excellent).

The reviews are shown in the following table:

Write a program that stores this data using a 2D array. Based on this information your program should allow the user to enter ratings for any three movies. The pro­gram should then find the reviewer whose ratings most closely match the ratings input by the user. It should then predict the user’s interest in the other movies by outputting the ratings by the reviewer for the movies that were not rated by the user. Use the Cartesian distance as the metric to determine how close the reviewer’s movie ratings are to the ratings input by the user. This technique is a simple version of the nearest neighbor classification algorithm.

For example, if the user inputs a rating of 5 for movie 102, 2 for movie 104, and 5 for movie 105, then the closest match is reviewer 0 with a distance of sqrt ((5 – 5)2 + (2 – 1)2 + (5 – 5)2) = 1. The program would then predict a rating of 3 for movie 100, a rating of 1 for movie 101, and a rating of 2 for movie 103.
