Please comment the code well and organize the classes so I can understand. Thank you!If solution if the one that is desirable, I will upvote! I really appreciate this, Bartleby!Waiting Times should not be negative. You sent back a solution but the waiting time was negative and that was incorrect.

Use C++ Programming Language. Objective Define a circular buffer data structure and test it. Problem Description: A circular buffer (also called a circular queue) is circular list of nodes where data items are added on one end of the buffer and removed from the other end. Because the nodes form a circular list, the list has no end or beginning: the tail node points to the head node, creating a ring of nodes. You may think of the nodes as containers or slots that are all initially empty but can be assigned a value in their data field info. Every time a new data item is inserted (inserting to a buffer is often referred as Writing), one slot is filled and the buffer has one less empty slot. Every time a data item is removed (referred to as Reading), the buffer has one more empty slot. Since the list has no beginning and no end, a pointer (writeIndex) is used to mark the next empty slot to write to and a second pointer (readIndex) is used to mark the next node to read from. The…
SHORTEST JOB FIRST SCHEDULINGAIM:To write a program to implement cpu scheduling algorithm for shortest job firstscheduling.ALGORITHM:1. Start the program. Get the number of processes and their burst time.2. Initialize the waiting time for process 1 as 0.3. The processes are stored according to their burst time.4. The waiting time for the processes are calculated a follows:for(i=2;i<=n;i++).wt.p[i]=p[i=1]+bt.p[i-1].5. The waiting time of all the processes summed and then the average time is calculate6. The waiting time of each processes and average time are displayed.7. Stop the program.

Implement SRTF (SJF with preemption) scheduling algorithm in C programming. NOTE: Please do not print the average waiting time and the average turnaround time. You are required to compute these for each process and print the values for each process separately. Add comments in the code so that the code is understandable. Take input from the user: the number of processes, their CPU burst times and arrival times for n number of processes. Compute and print the completion Time(CT), Turnaround Time(TAT), and Waiting Time(WT) for each process using C Programming
CPU Priority Scheduling-preemptive: Write a Java program to implement a priority scheduling algorithm that uses low number to represent high priority. Your program should first prompts the user to input a list of process ID, arrival time, burst time, and priority for each process to be run on the CPU. The list is terminated by 0 0 0 0 for the process ID, arrival time, burst time, and priority. The program output should draw a Gantt chart (as text) that shows the scheduling order of the processes using the Priority scheduling algorithm. Also print the turnaround time, response time, and waiting time for each process along with their average for all processes. Make sure to display very helpful messages to the user for input and output.
OZ PROGRAMMING LANGUAGE Exercise 1. (Efficient Recurrence Relations Calculation) At slide 54 of Lecture 10, we have seen aconcurrent implementation of classical Fibonacci recurrence. This is: fun {Fib X} if X==0 then 0 elseif X==1 then 1 else thread {Fib X-1} end + {Fib X-2} end end By calling Fib for actual parameter value 6, we get the following execution containing several calls ofthe same actual parameters.For example, F3, that stands for {Fib 3}, is calculated independently three times (although it providesthe same value every time). Write an efficient Oz implementation that is doing a function call for a givenactual parameter only once.Consider a more general recurrence relation, e.g.:F0, F1, ..., Fm-1 are known as initial values.Fn = g(Fn-1, ..., Fn-m), for any n ≥ m.For example, Fibonacci recurrence has m=2, g(x, y) = x+y, F0=F1=1

Sudoku is a popular logic puzzle that uses a 9 by 9 array of squares that are organized into 3 by 3 subarrays. The puzzle solver must fill in the squares with the digits 1 to 9 such that no digit is repeated in any row, any column, or any of the nine 3 by 3 subgroups of squares. Initially, some squares are filled in already and cannot be changed. For example, the following might be a starting configuration for a Sudoku puzzle: Create a class SudokuPuzzle.java Download SudokuPuzzle.java that has the attributes • board—a 9 by 9 array of integers that represents the current state of the puzzle, where 0 indicates a blank square • start—a 9 by 9 array of boolean values that indicates which squares in board are given values that cannot be changed and the following methods: • SudokuPuzzle—a constructor that creates an empty puzzle • toString—returns a string representation of the puzzle that can be printed • addInitial(row, col, value)—sets the given square to the given value as an…

Algorithms should follow the pseudo code standard described in handout 1. Your pseudo code should be placed in a code block, for example Algorithm alg_name(a, b) { // A description of the algorithm // input: a - a positive decimal integer; b - an integer // ouput: the sum of a and b c = a + b // or, c <- a + b return c } Do NOT change the template except the answer portion.
