C#. Using the Automobile class you created Chapter 10, Programming Exercise 5A as a base, derive a FinancedAutomobile class that contains all the data of an Automobile, plus the following field:
- AmtFinanced - The amount financed (a double)
Override the parent class ToString() method to include the child class’s additional data.
Create a program named AutomobileDemo2 that contains an array of four FinancedAutomobile objects. Prompt the user for all the necessary data, and do not allow duplicate ID numbers and do not allow the amount financed to be greater than the price of the automobile.
Sort all the records in ID number order and display them with a total price for all FinancedAutomobiles and a total amount financed. For example, the output should be in the following format:
Summary: FinancedAutomobile 1 2017 Honda Price is $26,000.00 Amount financed $12,000.00 FinancedAutomobile 4 2019 Honda Price is $36,000.00 Amount financed $0.00 FinancedAutomobile 5 2016 Toyota Price is $30,000.00 Amount financed $3,000.00 FinancedAutomobile 8 2018 Honda Price is $16,000.00 Amount financed $6,000.00 Total for all Automobiles is $108,000.00 Total financed all Automobiles is $21,000.00using System;

- PLEASE CODE IN PYTHON PLEASE USE CLASSES The game of Nim starts with a random number of stones between 15 and 30. Two players alternateturns and on each turn may take either 1, 2, or 3 stones from the pile. The player forced to take the laststone loses. Use object-oriented development to create a Nim2 application that allows the user to play Nim against the computer. The Nim2 application and its objects should: • Generate the number of stones to begin with. • Allow the player to go first. • Use a random number generator to determine the number of stones the computertakes. • Prevent the player and the computer from taking an illegal number of stones.
