Question

Implement the three methods, union, intersection, and difference, for the class ResizeableArrayBag. Note: the class ResizeableArrayBag presents an implementation of the ADT bag using a resizable array.

Answer 1

To implement the union, intersection, and difference methods for the ResizeableArrayBag class, you need to combine, find common elements, and find unique elements, respectively. Here is a step-by-step explanation of how to implement each method.

Step-by-step explanation:

In order to implement the union, intersection, and difference methods for the ResizeableArrayBag class, you will first need to understand how the ADT bag works. The ResizeableArrayBag class uses a resizable array to store elements. Here is a step-by-step explanation of how to implement each of these methods:

1. Union: To find the union of two bags, you need to combine all the elements from both bags into a new bag. This can be done by iterating over the arrays of both bags and adding each element to the new bag. Make sure to handle any resizing of the array if necessary.
2. Intersection: To find the intersection of two bags, you need to find the elements that are common to both bags. Iterate over one bag and check if each element is present in the other bag. If an element is found, add it to a new bag. Again, handle the resizing of the array if needed.
3. Difference: To find the difference between two bags, you need to find the elements that are present in one bag but not in the other. Iterate over one bag, checking if each element is present in the other bag. If it is not, add it to a new bag. Handle any resizing of the array as required.
