] ] has_perfect You are to write a function has "perfect (graph)" that takes in a BIPARTITE graph as its input, and then determintes whether or not the graph has a perfect matching. In other words, it will return the Boolean value True if it has one, and False if it does not. After compiling the above cell, you should be able to compile the following cell and obtain the desired outputs. print (has perfect({"A" : ["B", "C"], "B" : ["A", "D"], "C" : ["A", "D"], "D" : ["B", "C"]}), has perfect ( {"A" : ["B"], "B" : ["A", "D", "E"], "C" : ["E"], "D":["B"], "E": ["B","C","F"], "F":["E"]})) This should return True False Python Python
Subject Object oriented programming DO task in C++ Start with the safearay class from the ARROVER3 program in Chapter 8 of Object Orient programming by Rober Lafore. Make this class into a template, so the safe array can store any kind of data. Include following member functions in Safe array class. The minimum function finds the minimum value in array. The maximum function find the maximum value in array. The average function find average of all the elements of an array. The total function finds the running total of all elements of an array. In main(), create safe arrays of at least two different types int and double and store some data in them. Then display minimum, maximum, average and total of array elements. Note: use subscript ([]) operator in sasfearay class.

Moving Between Rooms - Navigation In this assignment, you will be working with a given "rooms" dictionary and associated constants to create a simple text-based game. Your main task is to develop a function that allows the player to navigate through the rooms based on the given specifications. You need to implement the function found in the starter code to the right The function should take into account the following conditions: If the direction leads to an exit, set the next room to the exit and the message to "Goodbye". If the direction is invalid, set the next room to the current room and the message to "No such direction". If the direction is valid, but you cannot go that way, set the next room to the current room and the message to "You bumped into a wall". If the direction is valid and you can go that way, set the next room to the room in that direction and the message to "Empty". To help you understand how the function will be integrated into the gameplay loop, the following…
write a program in c++(note:do not use sting data type) Create a class HugeIntegerthat uses a 40-element array of digits tostore integers as large as 40 digits each. Provide member functions input, output, add and subtract.For comparing HugeIntegerobjects, provide functions isEqualTo, isNotEqualTo, isGreaterThan,isLessThan, isGreaterThanOrEqualToand isLessThanOrEqualTo—each of these is a “predicate”function that simply returns true if the relationship holds between the two HugeIntegers and returnsfalse if the relationship does not hold.
Task 2: The formula for the area, A, of a triangle with sides of length a, b, and c is V[s(s – a)(s – b)(s – c)] A = Where (a + b + c) s = Write, test, and execute a function that accepts the values of a, b, and c as parameters from a calling function, and then calculates the values of s and [s(s - a)(s - b)(s - c)]. If this quantity is positive, the function calculates A. If the quantity is negative, a, b, and c do not form a triangle, and the function should set A = -1. The value of A should be returned by the function. Test the function by passing various data to it and verifying the returned value.
Exercise B: "Matrix Addition" For this exercise you will design and implement a function that takes two matrix arguments and computes their sum (if and only if a sum can actually be computed, returning an empty list otherwise). Two matrices can only be added together if they have exactly the same dimensions. If the dimensions are acceptable, then the matrix sum will have the same dimensions as either of the operands, and the value of each element in the matrix sum is itself the sum of the corresponding elements in the operand matrices. And although it does makes sense to test rectangularity before attempting addition, you need not perform this step (since you did it above). In order to complete this task, you will need to: ensure you know how matrix addition can be performed² ● Your submission for this exercise:
Ocaml programming 1. Create a type slidingTile, consisting of a char matrix and two integers xand y. The integers x and y are the coordinates of an empty tile. 2. Create a function val slide : slidingTile -> int -> int -> slidingTile = <fun> that given a slidingTile and two integers, that represent a location in thematrix, it slides the tile from the specied location to the empty tile, thenreturns the altered slidingTile. If provided location is not adjacent to theempty tile, or out of bounds, then return the slidingTile unaltered. 3. Create a function val print_tile : slidingTile -> unit = <fun> that prints a slidingTile on screen with the corresponding characters fromthe matrix. However, print an empty space where the empty tile is instead.
Problem 2: Create a ticket spin lock Complete the functions in ticket_spin_lock.cpp to implement a ticket lock that spins while waiting. Some useful hints: • The lock_t* lock struct containts the variables int ticket and int turn. • Use the atomic function_sync_fetch_and_add( int* ticket, int addition ). This function will atomically fetch the value in ticket and add addition to this value. • You may not need to do anything in the destroy function.
Write a program that will sort a prmiitive array of data using the following guidelines - DO NOT USE VECTORS, COLLECTIONS, SETS or any other data structures from your programming language. The codes for both the money and currency should stay the same, the main focus should be on the main file code (Programming language Java) Create a helper function called 'RecurInsSort' such that: It is a standalone function not part of any class from the prior lab or any new class you feel like creating here, Takes in the same type of parameters as any standard Insertion Sort with recursion behavior, i.e. void RecurInsSort(Currency arr[], int size) Prints out how the array looks every time a recursive step returns back to its caller The objects in the array should be Money objects added or manipulated using Currency references/pointers. It is OK to print out the array partially when returning from a particular step as long as the process of sorting is clearly demonstrated in the output. In…
Define a function SetBirth, with int parameters monthVal and dayVal, that returns a struct of type DateOfBirth. The function should assign DateOfBirth's data member numMonths with monthVal and numDays with dayVal.
create using c++ One problem with dynamic arrays is that once the array is created using the new operator the size cannot be changed. For example, you might want to add or delete entries from the array similar to the behavior of a vector . This project asks you to create a class called DynamicStringArray that includes member functions that allow it to emulate the behavior of a vector of strings. The class should have the following A private member variable called dynamicArray that references a dynamic array of type string. A private member variable called size that holds the number of entries in the array. A default constructor that sets the dynamic array to NULL and sets size to 0. A function that returns size . A function named addEntry that takes a string as input. The function should create a new dynamic array one element larger than dynamicArray , copy all elements from dynamicArray into the new array, add the new string onto the end of the new array, increment size, delete the…
