Consider the following set of processes, with the length of the CPU burst given in milliseconds:Process Brsut Time PrirorityP1 2 2P2 1 1P3 8 4P4 4 2P5 5 3The processes are assumed to have arrived in the order P1, P2, P3, P4, P5, all at time 0.Required:a. Draw four Gantt charts that illustrate the execution of these processes using the following scheduling algorithms: FCFS, SJF, nonpreemptive priority (a larger priority number implies a higher priority), and RR (quantum = 2).b. What is the turnaround time of each process for each of the scheduling algorithms in part a?c. What is the waiting time of each process for each of these scheduling algorithms?d. Which of the algorithms results in the minimum average waiting time (over all processes)?

Design a class tictactoe that: holds the following information about the game: two-dimensional array (3 by 3), and winner. add additional variables as needed. includes the functions to perform the various operations on objects. for example, function to print the board, getting the move, checking if move is valid, determining if there is a winner after each move. add additional operations as needed. includes constructor(s). write the functions of the class, and write a program that uses the class. the program should declare an object of type tictactoe. the program will create the board and store it in the array. the program will allow two players to play the tic-tac-toe game. after every valid move update the array, check if there is a winner. if there is no winner and no tie, then print the board again to continue.
