- What is a semaphore? What is the difference between a binary semaphore and a countingsemaphore? Show that if the wait and signal operations in a semaphore are not executedatomically, then mutual exclusion may be violated.Solve the following problems using Scala with Classic Akka Actors. For each problem, also implement client actors for sending the messages required for beginning the required computation. Use these client actors for testing your application actors. Recall the card shuffling problem. In a Faro shuffle, a stack of cards is broken up into two, and then combined so that a card from one sub-stack is followed by one from the other, and so on. A perfect Faro shuffle breaks up the stack into two sub-stacks of exactly the same size, and then combines them in the manner described above. An out-shuffle results in the top and the bottom cards of the stack remaining the same after the shuffle; an in-shuffle results in these cards becoming the second and the second last cards of the shuffled stack. Implement a shuffler actor which accepts a message containing a deck of cards as a list of even length, an integer indicating the number of times that the deck is to be shuffled, and a boolean…The algorithm for finding connected components in a graph is applied to eachof the three graphs. The output components are of different sizes, so split andmerge routines are applied to achieve a better partition to patches.
- An example of session design pattern implementation in a web application could be a loginsession:In this example, the Session class is implemented as a singleton, it has methods for logging in,logging out, checking authentication status and getting the user.The class implements a private constructor, which ensures that only one instance of the classcan be created, and a static method for retrieving the single instance.This way, the session object can be accessed from any part of the application, in order to checkthe user's authentication status, retrieve their user object and maintain their sessionthroughout the application.Implement the producer consumer problem (also known as bounded buffer problem) in java. create two threads i.e. the producer thread and the consumer thread. Create a shared buffer object using a LinkedList or Queue. The producer adds data to the buffer and the consumer removes data from the buffer. The producer cannot add data if the buffer is full and the consumer cannot remove data from the buffer if it is empty. Make sure there are no race conditions and deadlocks.Implement an postfix-to-infix translator using stacks. The applicationshould repeatedly read a postfix expression and print the equivalentinfix expression until the user quits. Throw an exception if the postfixexpression entered is invalid.
- Q: Consider a distributed implementation of a JavaSpace in which tuples are replicated across several machines. Give a protocol to delete a tuple such that race conditions are avoided when two processes try to delete the same tuple.Need Java Language solution asap Roni and Rajesh love to play a rope-based game. The game is as follows. At first, Tracy writes a long random thread on a white board. Then, each player starting with Roni takes turns. Each time, the player has to clear the corresponding subtitle in the dictionary. The dictionary contains N words. Indeed, a player who can clear any small bullet unit in his time loses a game, and another player is declared the winner. Note that after deleting a small R-string, the remaining small series is separated, i.e., they cannot erase the word that appears partially to the left of R and slightly to the right of R. Decide who wins the game, assuming both players play very well Input 1 bar 1 foo Output TracyModify the producer-consumer implementation code bellow, so that it uses monitors to handle race conditions instead of semaphores or mutexes. Use the pthread library implementation #include <pthread.h> #include <semaphore.h> #include <stdio.h> #include <stdlib.h> #define BUFFER_SIZE 20 pthread_mutex_t mutex; int count = 0; int buffer[BUFFER_SIZE]; pthread_t tid; int producers = 0, consumers = 0; void insert(int item) { while (count == BUFFER_SIZE); if (count < BUFFER_SIZE) { buffer[producers] = item; producers++; producers=producers%BUFFER_SIZE; sleep(1); } return; } int remove_item() { int item; while (count == 0); if (count > 0) { item = buffer[consumers]; buffer[consumers] = buffer[consumers - 1]; consumers++; consumers=consumers%BUFFER_SIZE; sleep(1); } return item; } void * producer(void *param) { int item; while (1) { item = rand() % BUFFER_SIZE; while (count >= BUFFER_SIZE);…

The program should be able to perform the following operations: Add persons details (first name, last name, phone number, city, address, sex and email) to the phone directory, where phone numbers in the directory have to be unique. (Note: each person record will store in one node in the linked-list and insert each person to the last) Delete any person details by a given phone number. Update telephone number by providing person first name. Display all details of persons from a phone directory. Search telephone number based on person first name. (Note: use sequential search to find all telephones for the given first name) Sort all persons in the phone directory ascending based on person first name. (Note: use bubble or selection sort to arrange the entire phone directory)Given the following code in Java and attached images( containing related code): //Controller (ONLY EDIT THE Controller.java file) import java.util.LinkedList; import java.util.Scanner; public class Controller { public Controller() { LinkedList<Stock> googList = new LinkedList<Stock>(); LinkedList<Stock> amazList = new LinkedList<Stock>(); Scanner input = new Scanner(System.in); do { System.out.print("Enter 1 for Google stock or 2 for Amazon, 3 to quit: "); int stockSelect = input.nextInt(); if(stockSelect == 3) break; System.out.print("Input 1 to buy, 2 to sell: "); int controlNum = input.nextInt(); System.out.print("How many stocks: "); int quantity = input.nextInt(); if(controlNum == 1) { System.out.print("At what price: "); double price =…
