Imagine you are developing a feature for an application that tracks user interests. Information about each user is stored in Redis as a set. Each user has a unique collection of interests.

1. Add the interests for each user to their respective sets :

   • user:1:interests : " music ", " movies ", " sports ";

   • user:2:interests : " sports ", " travel ", " reading ";

   • user:3:interests : " reading ", " music ", " cooking ".

2. Check if User 1 is interested in " travel " and if User 2 is interested in " sports ";

3. Identify the common interests of User 1 and User 2 ;

4. Find the interests of User 1 that are not shared by User 2 ;

5. Create a list of all unique interests shared by User 1 , User 2 , and User 3 ;

6. User 3 has stopped being interested in " music ." Remove this interest from their set ;

7. Display the list of interests for each user after performing these operations.
