First, the directorys:

• children: contains a Child, which is a Visitable Class used for storing children information, extended by the Baby, Kid and Teen classes, which are instantiated using the Factory Class ChildrenFactory

• input: contains all the classes that deal with the Input Product Class contains the information regarding a gift Change Class contains the information regarding a yearly change UpdateGiftList is Utility Class used for applying a yearly change InputLoader Class is used as a database for the Input

• output: contains a Singleton Class used as a database for the Ouput and has the exact structure as the json output file

• santa: contains the classes that deal with handing out gifts to the children Santa Class calculates a child's budget and assigns him presents Child Visitor is an interface for all the Child Visitors, implemented only by AverageScoreVisitor for the moment AverageScoreVisitor is a Visitor class which calculates a Child's average nice score based on his history

The flow of the app:

The Main Class coordinates the whole program The input is read using Jackson from json files Each test is split into 2 parts: the initial data phase and the changes phase

After the initial data phase and after each annual change is applied, a new set of children are created using the Factory Method, they can be either Baby, Kid or Teen, and based on that the AverageScoreVisitor class calculates their average nice score and then Santa assigns every Child a present

niceScoreBonus -> implemented inside the AverageScoreVisitor class, pretty simple

Elves -> "white" is ignored, -> "black" and "pink" are implemented using Strategy Pattern, inside ElfBudgetStrategy folder -> "yellow" is implemented as part of Santa, all the children with the yellow elf are stored inside a list after Santa assigns gifts, this list is parsed, and every eligible child gets a gift

Now the problem is that I was keeping a list with the cheapest gifts from every category, if a gift goes out of stock, this list updates, but the yellow elf assigns a gift only if the cheapest gift from the most like category of the child is still in stock. So I created a HashSet containing all the cheapest out-of-stock gifts.

Strategy -> "id" is ignored, the children are always sorted based on id at the start of a test / after a change, it's just that the other strategies don't apply, like not using one at all -> "niceScore" and "niceScoreCity" are implemented using Strategy Pattern, inside GiftAssignStrategy -> for the city scores, I keep a map with every city and it's scores, and a map with every city and the number of children in that city, after completing these 2 maps, I calculate the niceScoreCity for each kid
