What is the new maximum problem size achievable for an algorithm with a running time of 2^n, assuming it is run on a computer 256 times faster than the previous one?
2^m
A double-ended queue (deque) is a data structure that supports insertion and deletion at:
both the front and the rear of the queue
What is the time complexity of an algorithm with a running time of 400n?
O(n)
What is the primary advantage of using a computer that is 256 times faster than the previous one?
it can solve larger problems in the same amount of time
What is the purpose of the insertFront(e) function in a deque?
to insert a new element at the beginning of the deque

Name and score
What is not mentioned as a possible extension to the high score entry object?
Player's age
What data structure is not mentioned in the provided text?
Queue
What is the purpose of using arrays in this context?
To store and access data using integer indices
What is not a mentioned application of arrays?
Implementing a sorting algorithm
What is a key difference between a circularly linked list and a doubly linked list?
A circularly linked list is linked into a cycle, while a doubly linked list is not.
What is a limitation of the simple implementation of a doubly linked list provided?
All of the above
What type of mechanism would allow for accessing arbitrary elements of a list?
Iterators
What would be a more robust implementation of a doubly linked list?
One that throws an exception when an attempt is made to access or remove elements from an empty list.
What is NOT provided in the simple implementation of a doubly linked list?
A mechanism for accessing elements in the middle of the list.
What type of data structure would be useful for implementing a mechanism for accessing arbitrary elements of a list?
Iterator
This quiz covers the basics of a simple doubly linked list implementation, its limitations, and the need for additional features such as error checking and iterators. It discusses the responsibilities of the user and the possibilities for future improvements. Learn about the potential extensions to this data structure.
