Following is the implementation of the class Task (slightly modified from. class Task: definit__(self, title, completed, required_taskers) -> None: self.title= title #String self.completed = completed #Boolean- True/False self.required_taskers = required_taskers #Integer 1. Write a modified version of the class Task so that every Task() object created is stored in a list object titled_list_of_tasks of the class TaskList()) 2. Write a method task-total () of the class TaskList() that returns the total number of completed tasks (an integer) and the total number of required taskers (an integer)

i am writing a code in python in order to create an employee management application for a fictional paper company. Each employee is represented by 3 attributes: name, age and position I need to define and use the following functions display_employees(): (this needs a loop inside of the function) allocate_department (returns single list containing information) display_department_employees() (needs a loop inside of this function and uses allocate_department) head_of_department() (uses allocate_department and need to use a loop inside of this function) display_department_employees() (function that displays all info for all department.

Write Java code Objectives •Use an abstract data type for a list •Use a method that contains an Object type as a formal parameter •Use methods in an existing class •Access data members within a class Required Files: •ListInterface.java •ListException.java •ListOutOfBoundsException.java •ListArrayBased.java Description A list is an abstract data type used to store ordered data, and contains operations that fall into the following categories: (1) add data to a data collection, (2) remove data from a data collection, and (3) ask questions about data in a data collection. The operations which ask questions about the data in a data collection may include operations that determine if a data collection is empty, determine the size of a data collection, and retrieve the item at a given position in a data collection. A list should be able to contain any type of object. The methods for the List support any object as specified in the interface. In this assignment, the objects will be S trings.…
typedef struct node_t node_t; struct node_t { }; int32_t value; node_t* next; node_t* insert (node_t* list, int32_t v, int32_t* flag); 3) As you may have noticed from MT1, Howie is lazy. He wants you to write the interface for the following implementation of function copy_to_linked_list. He really appreciates your help! /* copy_to_linked_list int32_t copy_to_linked_list (int32_t a[], int32_t size, node_t** list_p) { int32_t flag, i; for (i = 0; i < size; ++i) { *list_p = insert (*list_p, a[i], &flag); if (-1== flag) return -1; } return 0;
Write a function called find_duplicates which accepts one list as a parameter. This function needs to sort through the list passed to it and find values that are duplicated in the list. The duplicated values should be compiled into another list which the function will return. No matter how many times a word is duplicated, it should only be added once to the duplicates list. NB: Only write the function. Do not call it. For example: Test Result random_words = ("remember","snakes","nappy","rough","dusty","judicious","brainy","shop","light","straw","quickest", "adventurous","yielding","grandiose","replace","fat","wipe","happy","brainy","shop","light","straw", "quickest","adventurous","yielding","grandiose","motion","gaudy","precede","medical","park","flowers", "noiseless","blade","hanging","whistle","event","slip") print(find_duplicates(sorted(random_words))) ['adventurous', 'brainy', 'grandiose', 'light', 'quickest', 'shop', 'straw', 'yielding']…
PYTHON LAB: Inserting an integer in descending order (doubly-linked list) Given main.py and an IntNode class, complete the IntList class (a linked list of IntNodes) by writing the insert_in_descending_order() method to insert new IntNodes into the IntList in descending order. Ex. If the input is: 3 4 2 5 1 6 7 9 8 the output is: 9 8 7 6 5 4 3 2 1 _____________________________________________________________________________________ Main.py: from IntNode import IntNode from IntList import IntList if __name__ == "__main__": int_list = IntList() input_line = input() input_strings = input_line.split(' ') for num_string in input_strings: # Convert from string to integer num = int(num_string) # Insert into linked list in descending order new_node = IntNode(num) int_list.insert_in_descending_order(new_node) int_list.print_int_list() IntNode.py class IntNode: def __init__(self, initial_data, next = None,…
You have a sorted linked list. Fill in the missing code in the following function. SortedType::DeleteItem(Item Type item) // pointer delete //trailing pointer // traveling pointer void { NodePtr tempPtr; NodePtr predLoc; NodePtr location: bool found false; // Find item to delete: Put your code below //delete item: Put your code below
Add the following functions and write a program to test these functions in the class linkedListType: a. Write the definition of a function that returns the data of the kth element of the linked list. If such element is not exist in the list, exit the program. b. Write the definition of a function that deletes the kth element of the linked list. If such element does not exist in the list, exit the program and display message as output.
C++ Code for a QueueThe program should features a Queue class with insert(), remove(), peek(),isFull(), isEmpty(), and size() member functions.The main() program creates a queue of five cells, inserts four items, removes threeitems, and inserts four more. The sixth insertion invokes the wraparound feature. All the items are then removed and displayed. The output looks like this:40 50 60 70 80
Part 5. Operator Overload: add Next, you will add the ability to use the addition operator (+) in conjunction with Simpy objects and floats. You will implement add such that the left-hand side operand of an addition expression can be either a simpy object or a float value using a Union type. The add_method should return a new Simpy object and should not mutate the object the method is called on. When the right-hand side of an addition expression is also a simpy object, you should assert that both objects' values attributes have equal lengths. Then, you should produce a new simpy object where each item in its values attribute corresponds to the items of the original Simpy objects at the same index added together. For example: a = Simpy([1.0, 1.0, 1.0]) b = Simpy([2.0, 3.0, 4.0]) c = a + b print(c) # Output: Simpy([3.0, 4.0, 5.0]) When the right-hand side of an addition expression is a float value, you should produce a new simpy object where each item corresponds to the item at the same…
@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.
Having trouble with creating the InsertAtEnd function in the ItemNode.h file below. " // TODO: Define InsertAtEnd() function that inserts a node // to the end of the linked list" Given main(), define an InsertAtEnd() member function in the ItemNode class that adds an element to the end of a linked list. DO NOT print the dummy head node. Ex. if the input is: 4 Kale Lettuce Carrots Peanuts ------------------------------------------------------- main.cpp -------------------------------------------------------- #include "ItemNode.h" int main() { ItemNode *headNode; // Create intNode objects ItemNode *currNode; ItemNode *lastNode; string item; int i; int input; // Front of nodes list headNode = new ItemNode(); lastNode = headNode; cin >> input; for (i = 0; i < input; i++) { cin >> item;…
