Explanation of Solution
Specifying the class type:
- • List refers to a predefined data structure in C# which stores objects of the class type.
- • A list can hold any data type such as integer, float, string or even a complex data type.
- • For example, the declaration to specify a list that stores the objects of the class type is given...

- card_t * moveCardBack (card t *head); The moveCardBack function will take the card in front of the pile and place it in the back. In coding terms, you are taking the head of the linked list and moving it to the end. The function has one parameter which is the head of the linked list. After moving the card to the back, the function returns the new head of the linked list.arrow_forwardAn iterable is an object that is similar to a list and is created by the range function True or Falsearrow_forward@6 The Reference-based Linked Lists: Select all of the following statements that are true. options: As a singly linked list's node references both its predecessor and its successor, it is easily possible to traverse such a list in both directions. According to the terminology introduced in class, the head reference variable in a singly linked list object references the list's first node. According to the terminology introduced in class, in a doubly linked list, each node references both the head and tail node. In a double-ended singly linked list, the tail reference variable provides access to the entire list. In a circular linked list, the last node references the first node.arrow_forward
- Scores Class Write a class named Scores which should have the following attribute: • _scores (a list to hold test scores, 0 - 100. Initially empty. ) The Scores class should have an _init__ method that creates the _scores attribute. It should also have the following methods: • add_score: this method adds a score to the __scores list. It accepts a single score as it's' only argument. • get_average: this method accepts no arguments. If _scores is empty, this method returns -1. Otherwise, it returns the average of all scores in _scores. • get_high_score: this method accepts no arguments. if scores is empty, this method returns -1. Otherwise, it returns the highest score in __scores. • get_low_score: this method accepts no arguments. if scores is empty, this method returns -1. Otherwise, it returns the lowest score in scores. • _str_: This method returns a string similar to the following (assuming the _scores contains 89, 77, 93): Once you have written the class, write a program that…arrow_forwardPart 2. fill Method Define a method in simpy named fill. Its purpose is to fill a simpy's values with a specific number of repeating values. The fill method will have two parameters following self: 1. The float value you are filling the values list in with. 2. The int number of values to fill in. The fill method is procedure-like in that it returns None and mutates the object the method is called on. After calling fill, the length of the Simpy object's values should be equal to the second argument given to fill. For example, consider the following usage and expected printed output, given inline, below: twos = Simpy([]) twos.fill(2.0, 3) print("Actual: ", twos, Expected: Simpy([2.0, 2.0, 2.0])") twos.fill(2.0, 5) print("Actual: ", twos, " - Expected: Simpy([2.0, 2.0, 2.0, 2.0, 2.0])") mixed = Simpy([]) mixed.fill(3.0, 3) - Expected: Simpy([3.0, 3.0, 3.0])") print("Actual: ", mixed, mixed.fill(2.0, 2) print("Actual: ", mixed, Expected: Simpy ([2.0, 2.0])") Pythonarrow_forwardaddCourse: accepts an object of type Course as the first parameter and the idNum of the Student as the second parameter.
