Chapter 4, Problem 51E

Rewrite getLot so that it does not rely on a lot with a particular number being stored at index (number-1) in the collection. For instance, if lot number 2 has been removed, then lot number 3 will have been moved from index 2 to index 1, and all higher lot numbers will also have been moved by one index position. You may assume that lots are always stored in increasing order according to their lot numbers.

How do I add several objects to an ArrayList in JAVA using a loop?
This project is divided into two parts. Part 1. You will be implementing a dictionary structure (storing pairs key/value), and reading the user input to manipulate the structure. The commands implemented in that stage are put, get, and del. It will be important not to leak any memory in these functions. Part 2. You will add two more commands: clr, which clears the dictionary, and siz, which prints the size of the dictionary. Again, clr will have to make sure not to leak any memory. You will also implement a destructor for your dictionary object.   The dict.c file that the problems need to be solved is in the image given
In this lab, you will create a backend class called SortableSet. A set, in computer science, is an unordered collection of unique objects. In our SortableSet, all of the objects in the set will also be immutable at the set level. This means that even if the data class used to create objects is not immutable, once they are in the set they are. We do this by making a deep copy of any objects being added to the set or returned from the set. The objects stored in the SortableSet must implement an interface called Sortable that provides a numeric sorting key and a deep copy method. SortableSet also takes advantage of two custom exception classes: DuplicateException and InvalidKeyException. Finally, the "sortable" part of SortableSet is implemented by a getSortedList method that makes a deep copy of every object in the set, saves them to an array, and then sorts them based on each object's sorting key. The sort algorithm used is a recursive radix sort modified to work with objects.
