What advantage does a circular linked structure with a dummy header node give the programmer?
1. What advantage does a circular linked structure with a dummy header node give the programmer? 2 Describe one benefit and one cost of a doubly linked structure, as compared to a singly linked structure. 3. Examples of linear collections are a sets and trees b lists and stacks 4. Examples of unordered collections are […]
Add the methods insert and remove to the Array class.
Add the methods insert and remove to the Array class. These methods should use the strategies discussed in this chapter, including adjusting the length of the array, if necessary. The insert method expects a position and an item as arguments and inserts the item at the given position. If the position is greater than or […]
Add an instance variable _logicalSize to the Array class.
1. Data in a singly linked structure are contained in a cells b nodes 2. Most operations on singly linked structures run in a constant time b linear time 3. It requires constant time to remove the first item from a(n) a array b singly linked structure 4. Add an instance variable _logicalSize to the […]
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 […]
