Develop a Matrix class that uses the built-in operators for arithmetic in a manner similar to the Rational number class discussed in Chapter 8.

1. Jill tells Jack that he should now remove the current implementation of the __iter__ method from the Array class, if it’s really behaving like a list. Explain why this is a good suggestion. Also explain how the __str__ method should be modified at this point.

2. A Matrix class can be used to perform the some of the operations found in linear algebra, such as matrix arithmetic. Develop a Matrix class that uses the built-in operators for arithmetic in a manner similar to the Rational number class discussed in Chapter 8. The Matrix class should extend the Grid class.

The next four projects ask you to define some functions for manipulating linked structures. You should use the Node and TwoWayNode classes, as defined in this chapter. Create a tester module that contains your function definitions and your code for testing them.

Suggest a modification of the binary search algorithm that emulates this strategy for a list of names.

1. Suppose that a list contains the values 20 44 48 55 62 66 74 88 93 99 at index positions 0 through 9. Trace the values of the variables….

Explain why insertion sort works well on partially sorted lists.

1. Which configuration of data in a list causes the smallest number of exchanges in a selection sort? Which configuration of data causes the largest number of exchanges? 2. Explain….

Draw a class diagram that shows the relationships among the classes in this new version of the system

Jack decides to rework the banking system, which already includes the classes BankView, Bank, SavingsAccount, and RestrictedSavingsAccount. He wants to add another class for checking accounts. He sees that savings….
