Which of the following best illustrates the principle of indemnity in insurance?

What is the value of numbers after this code runs? numbers = [1, 2, 3] numbers.append(4)

Write a Python class named SimpleQueue that uses a Python list internally. Your class must include: • an __init__ method that creates an empty list • an enqueue(value) method that adds value to the rear • a dequeue() method that removes and returns the front value • an is_empty() method that returns True when the queue is empty Then write a few lines of code that create a SimpleQueue, enqueue 10, 20, and 30, dequeue one value, and print the remaining internal list. You may assume dequeue() will not be called on an empty queue.

If the input size doubles for an O(n²) algorithm, the amount of work grows by approximately:

A queue currently contains [10, 20, 30], where 10 is at the front. Which value should dequeue remove?

Use a Python list as a stack. Write code that: 1. Creates an empty stack. 2. Pushes 10, 20, and 30 in that order. 3. Pops one value. 4. Prints the remaining stack. The printed result should be: [10, 20]

Which statement best describes an abstract data type (ADT)?

Write a function named is_balanced(lst) that returns True if lst contains an even number of elements and False otherwise. Examples: is_balanced([1, 2, 3, 4]) returns True is_balanced([1, 2, 3]) returns False Provide the complete function. Part #2.  What is the Big-O time complexity of your function?  Why?

Suppose the class Dog has already been defined. After x = Dog(), what is x?

Which data structure is the most natural choice for an undo feature?
