The document describes a class called unorderedSetType that is derived from unorderedArrayListType to represent sets. The class redefines functions like insertAt, insertEnd, and replaceAt to handle sets appropriately by checking for duplicate elements. It also includes set operations like union and intersection. A program is provided to test the unorderedSetType class.

1. (Unordered Sets) As explained in this chapter, a set is a collection of distinct elements of the
same type. Design the class unorderedSetType, derived from the class unorderedArrayListType,
to manipulate sets. Note that you need to redefine only the functions insertAt, insertEnd, and
replaceAt. If the item to be inserted is already in the list, the functions insertAt and insertEnd
output an appropriate message. Similarly, if the item to be replaced is already in the list, the
function replaceAt outputs an appropriate message.Include the set operations of union and
intersection in your class. Also write a program to test your class. (C++)
