to take advantage of your programming skills in order to keep your
memories organized. You want to develop an application to keep
track of your photos. You have decided to assign categories to
photos as i) friends, ii) family and iii) trips. You also don’t
want these categories to be fixed; you want to start gym soon and
you will be adding some more categories like sports and fitness
etc. Some of your photos can belong to more than one category like
a trip with friends will go to both Friends and trips.
You have decided to
use a s​ingle linked list, Double Linked
list ​ for each category in order to keep track of your
