Question
Chapter 8.4, Problem 28STQ
Program Plan Intro
Overriding method:
- • If the subclass inherits a method from its superclass, the overriding method is possible. The overriding method is used to define a methods or behavior that’s specific to the superclass type.
- • Based on the requirement, subclass can be implemented a superclass method.
- • Generally, the overriding method overrides the functionality of a current method.
- • The private method can’t override, because this method can’t accessible outside the class.

Please answer the following question in Python code:
Inheritance (based on 8.38) You MUST use inheritance for this problem. A stack is a sequence container type that, like a queue, supports very restrictive access methods: all insertions and removals are from one end of the stack, typically referred to as the top of the stack. A stack is often referred to as a last-in first-out (LIFO) container because the last item inserted is the first removed. Implement a Stack class using Note that this means you may be able to inherit some of the methods below. Which ones? (Try not writing those and see if it works!)
Constructor/_init__ - Can construct either an empty stack, or initialized with a list of items, the first item is at the bottom, the last is at the top.
push() – take an item as input and push it on the top of the stack
pop() – remove and return the item at the top of the stack
isEmpty() – returns True if the stack is empty, False otherwise
[] – return the item at a given…
In C++, can I get a code example for a function that will return the intersection items for two sets. It will return/print out the shared (intersection) items for them. I am looking for an actual function preferably for a set class, comparing one instance of a set class with another, but definitely NOT a STL keyword. Thank you.

- Mixed Fraction Arithmetic Java Project: Problem Description: Make a java program that facilitates addition, subtraction, multiplication, and division of mixed numbers (similar with the first activity) but this time all of the inputs /outputs may involve fractions, mixed fractions, or a combination. Points to consider: MixedFraction class must override the operations (add, subtract, multiplyBy, divideBy) inherited from Fraction class to have a different implementation if the MixedFraction object will have a Fraction object as parameter in performing the required operation, On top of that, the inherited operations must also be overloaded to allow a MixedFraction object to accept other parameters such as a whole number or another MixedFraction object. The toString method which is inherited must also be overridden by MixedFraction to have a more appropriate return value. Further formatting must also be considered such that if the result of the operation has a zero value for the whole…arrow_forwardProgramming Exercise 8 asks you to redefine the class to implement the nodes of a linked list so that the instance variables are private. Therefore, the class linkedListType and its derived classes unorderedLinkedList and orderedLinkedList can no longer directly access the instance variables of the class nodeType.

In main(), you will then instantiate (i.e., create) several fairy objects (from the derived classes ONLY), but no more than 5. When the user encounters a fairy, the fairy will state his/her name and ask what the user wants. In response, the user may: Ask for a wish, Offer to help the fairy, or Say goodbye to the fairy. The user will continue to interact with the fairy until the user chooses the final option, saying goodbye to the fairy. Once the user says goodbye, the game moves on to the next fairy. After the user has encountered all of the fairies, the game is over and the user's points total is displayed. Specifications All interaction will occur through standard input and standard output.

Assume you are a developer working on a class as part of a software package for running artificial neural networks. The network is made of Nodes (objects that implement a Node interface) and Connections (objects that implement a Connection interface). To create a new connection you call the constructor for a concrete class that implements the Connection interface, passing it three parameters: Node origin, Node target, and double weight. The weight is a double that is greater than or equal to 0, and represents how strongly the target node should weigh the input from the origin node. So with a weight of 0.1 the target node will only slightly weight the input from the origin, but with a weight of 725.67 the target node will strongly weight the input.
