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)

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,…
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…
