DiceSet Class in Python
Write a class named DiceSet that contains a list of Die objects.
Fields
dice
a list of Die objects Methods
__init__(self, dice_faces)
The constructor should instantiate the dice list to an empty list if no parameters are set.
The constructor should take a list of integers. Add one die to the dice set for each integer with the number of faces equal to the integer.
pop_die(self, value)
Remove and return the first die with the given value from the list.
add_die(self, die)
Adds the given die (of class Die) to the dice list.
roll(self)
Roll all the die objects in the list of dice and return their sum.
die_values(self)
Return a list of the int values (last rolls) of the dice in the list.
__str__(self)
returns a string version of a dice set. Example: "{[d3] 1, [d6] 4, [d12] 5, [d4] 3}"
TRUE OR FALSE
In order to use static methods in Collections, we must create a Collection object using a new operator.
Salesforce Assignment:
You are working in company as a junior developer and the manger assign you a task to create the
test class of trigger code of the following code will cover all the use case like insert, update, delete.
The code is as follows:
public class TriggerBasicAssignmentTriggerHelper (
// This method is used to update the vlaue of field C
public static void getFiledvalue(List listofValues, Map mapofCoustomobject ){
for (Trigger_Basic_Assignments_ct :listofvalues){
if(mapofCoustomobject == null || t.Field_A_c != mapofCoustomobject.get(t.Id). Field_A_C || t.Field_8_c != mapofCoustomobject.get(t.I
if(t.Operator_ '+')
t.Field C_c = t.Field_A_c + t.Field_B_c;
else if(t.Operator_c *')
t. Field C_c = t.Field A_* t.Field_8_c;
else if(t.Operator_c == /' && t.Field B_c != 0)
t.Field C_c = t.Field A_c / t.Field_B_c;
else
t.Field C_c = t.Field_A_c - t.Field B_c;
I need the test class only.

- PyCharm Programming! A Game object knows its name and the number of avators is currently has. It is initialized without Avatars objects. It has a method startGame, which initializes an internal empty list of Avator objects. It has a method to add one Avator object at a time to the Game. It also has a method to remove an Avatar object by the Avatar’s name. A Game object also has a method to animate all its current Avatar objects. Furthermore, it has a method to stopGame, which destroys all current Avator objects in its internal list. The Avatar class creates simple human-type Avatars, which have attributes such as name, hair color, height, superpower. An Avatar object can change its hair color and superpower. It also has a method that “animates” the avatar. The animate() method should simply be a print message such as “Hello! I am …!

The code to do this can be copied from here:ListNode *nodePtr, *previousNode = nullptr; Part 1: Your own Linked ListDesign your own linked list class to hold a series of integers. The class should have member functions for appending, inserting, and deleting nodes. Don't forget to add a destructor that destroys the list. Demonstrate the class with a driver program.Part 2: List PrintModify the linked list class you created in part 1 to add a print member function. The function should display all the values in the linked list. Test the class by starting with an empty list, adding some elements, and then printing the resulting list out.arrow_forward
