- Round-Robin (RR): Write a Java program to implement a Round-Robin (RR) scheduling algorithm with quantum q that will be entered by user. Your program should first prompts the user to input a list of process ID, arrival time, and burst time (in ms) for each process to be run on the CPU. The list is terminated by 0 0 0 for the process ID, arrival time, and burst time. The program output should draw a Gantt chart (as text) that shows the scheduling order of the processes using the RR scheduling algorithm. Also print the turnaround, response, 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.To better understand the concept of recursion, let’s look at an example that’s quite familiar to computerusers—the recursive definition of a file-system directory on a computer. A computer normally stores related filesin a directory (also called a folder). A directory can be empty, can contain files and/or can contain other directories,usually referred to as subdirectories. Each of these subdirectories, in turn, may also contain both files anddirectories. If we want to list each file in a directory (including all the files in the directory’s subdirectories), weneed to create a function that first lists the initial directory’s files, then makes recursive calls to list the files in eachof that directory’s subdirectories. The base case occurs when a directory is reached that does not contain anysubdirectories. At this point, all the files in the original directory have been listed, and no further recursion isnecessary. Write a print_directory function that recursively walks through the…You were asked to design a smart control unit for a printer. The printer can print three types of documents: pdf, MSWord, and JPG (images).The smart printer keeps the documents sent for printing in a queue. It can perform 2 types of operations on the jobs in the queue. These are:(1) Add colored frame, which displays a colored frame on the edges of the printed paper. (2) Add background, which adds some background on the printed paper.The control unit should be designed in a way that allows clients to perform any operation on the jobs in the queue. So the problem is that you have a collection of heterogeneous objects, on which you want to perform similar operations. The design also allows adding more operations upon client's needs.Which design pattern best fits the problem above? 1)Iterator2)Command3)Strategy4)Visitor
- Suppose a program runs in on a computer with multiply operations responsible for 90% of the execution time. What is the overall speedup achieved if the speed of multiply operations is improved by 16? How much do we have to improve the speed of multiplication if i want my program to run four times faster?Textbook examples show a task that is waiting at a rendezvous for another task to arrive in a continuous loop. What non-busy waiting method is really being used? pick one: a) an explicit wait to be put in place. b) A wait stack is checked after each interaction instead of a constant repeat check as in a loop c) every iteration, a continuation is checked d) a queue is searched every iteration.The Java Virtual Machine (and your computer’s assembly language) support a goto instruction so that the search can be “wired in’’ to machine code, like the program at right (which is exactly equivalent to simulating the DFA for the pattern as in KMPdfa, but likely to be much more efficient). To avoid checking whether the end of the text has been reached each time i is incremented, we assume that the pattern itself is stored at the end of the text as a sentinel, as the last M characters of the text. The goto labels in this code correspond precisely to the dfa[] array. Write a static method that takes a pattern as input and produces as output a straight-line program like this that searches for the pattern. Straight-line substring search for A A B A A A int i = -1;sm: i++;s0: if (txt[i]) != 'A' goto sm;s1: if (txt[i]) != 'A' goto s0;s2: if (txt[i]) != 'B' goto s0;s3: if (txt[i]) != 'A' goto s2;s4: if (txt[i]) != 'A' goto s0;s5: if (txt[i]) != 'A' goto s3; return i-8;
- This is some code in C for quicksort. The quicksort works correctly, but I am trying to implement multithreading. I am trying to run the recursive calls in parallel with a limit on how much threads can be running at one time (set by the global variable 'maximumThreads'). My logic is incorrect with managing how many threads can be ran at the same time. The part that I need you to look at is after the for loop in quick sort, where I have my logic for the mutex and the conditional variable. Right now when I run my code, the program runs without stopping. I would like help with correctly implementing this. #include <stdlib.h>#include <string.h>#include <pthread.h>#include <stdio.h>#define SORT_THRESHOLD 40typedef struct _sortParams {char** array;int left;int right;int* currentThreads;pthread_mutex_t* mutex;pthread_cond_t* cond_var} SortParams;static int maximumThreads; /* maximum # of threads to be used *//* This is an implementation of insert sort, which although…This is some code in C for quicksort.

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.

- No need for the whole code --> just write the instruction in java We are working with a circular linked list that is referenced by a tail reference, i.e., a reference to the last node of the linked list. There is no head or size information about the linked list. Node is declared as: Node { int value; Node next; } There are four parts in this problem. Don't forget to deal with special cases for each part. Write instructions to insert a node newNode at the beginning of the circular linked list. Write instructions to insert a node newNode at the end of the circular linked list. Write instructions to delete the first node of the circular linked list. Write instructions to delete the last node of the circular linked list.How does changing the number of threads (-n) change the outcome of theprogram? Are there any values of-nthat ensure no deadlock occurs?2. Implement the frame replacement algorithm for virtual memory In Java For this task, you need to perform the simulation of page replacement algorithms. Create a Java program which allows the user to specify: • the total of frames currently exist in memory (F), the total of page requests (N) to be processed, • the list or sequence of N page requests involved, For example, if N is 10, user must input a list of 10 values (ranging between 0 to TP-1) as the request sequence. Optionally you may also get additional input, the total of pages (TP) This input is optional for your program/work. It only be used to verify that each of the page number given in the request list is valid or invalid. Valid page number should be within the range 0, .. , TP-1. Page number outside the range is invalid. Then use the input data to calculate the number of page faults produced by each of the following page replacement algorithms: • First-in-first-out (FIFO) - the candidate that is the first one that entered…
