- You will create a number of threads—for example, 100—and each thread sleep for a random period of time, request a pid, sleep again for a random period of time, and then release the pid. Sleeping for a random period of time approximates the typical pid usage in which a pid is assigned to a new process, the process executes and then terminates, releasing the pid on the process's termination. You should use a linked list to store the pids. On UNIX and Linux systems, sleeping is accomplished through the sleep() function, which is passed an integer value representing the number of seconds to sleep. The number of threads to create as well as the maximum sleep time will be passed on the command line as: For example: ./a3q3 100 15 This represents 100 threads, each with a random sleep time of up to 15 seconds. Code that compiles and runs with correct logic will be evaluated for full marks even if they present some instability (e.g. segmentation fault errors).Exception in thread "main" java.lang.NumberFormatException: For input string: "x" for Java code public class Finder { //Write two recursive functions, both of which will parse any length string that consists of digits and numbers.

- Hello Can you please help me with this code because I am struggling how do to this, can you please help me this code has to be in C. Write a multithreaded program that calculates various statistical values for a list of numbers. This program will be passed a series of numbers on the command line and will then create three separate worker threads. One thread will determine the average of the numbers, the second will determine the maximum value, and the third will determine the minimum value. For example, suppose your program is passed the integers 90 81 78 95 79 72 85 The program will report The average value is 82 The minimum value is 72 The maximum value is 95 The variables representing the average, minimum, and maximum values will be stored globally. The worker threads will set these values, and the parent thread will output the values once the workers have exited. (We could obviously expand this program by creating additional threads that determine other statistical values, such as…You'll write a C++ program to demonstrate thread synchronization. Your main function should first create an empty file called *sync.txt*. Then it will create two separate threads: *Thread-A* and *Thread-B*. Both threads will open *sync.txt* and write to it simultaneously. *Thread-A* will write the numbers 0 through 9, a total of fifty-thousand times in nested `for` loops, then exit. In other words, print the numbers 0 through 9 over and over again, with each run on a separate line, for 50,000 lines. Here's an example of one such line: ```text 0 1 2 3 4 5 6 7 8 9 ``` Somewhat similarly, *Thread-B* will write the letters A through Z fifty-thousand times in nested `for` loops, then exit. In other words, print the letters A through Z over and over again, with each run on a separate line, for 50,000 lines. Here's an example of one such line: ```text A B C D E F G H I J K L M N O P Q R S T U V W X Y Z ``` Do not write each line as one long string. You must write each character to the…USE SIMPLE PYTHON CODE TO COMPLETE Basic version with two levels of threads (master and slaves) One master thread aggregates and sums the result of n slave-threads where each slavethread sums a different range of values in an array of 1000 random integers (please program to generate 1000 random integers to populate the array). The number of slave-threads is a parameter which the user can change. For example, if the user chooses 4 slave threads, each slave thread will sum 1000/4 = 250 numbers. If the user chooses 3 slave threads, the first two may each sum 333 numbers and the third slave threadsums the rest 334 numbers. 2) Advanced version with more than two levels of threadsThe master thread creates two slave-threads where each slave-thread is responsible to sum half segment of the array. Each slave thread will fork/spawn two new slave-threads where each new slave-threadsums half of the array segment received by its parent. Each slave thread will return the subtotal to its parent…

Exercise 3: Read the following code and try to guess what will be its output. import java.util.*; class Car { private int speed; public void…Arrays in Java are objects that use reference semantics. Explain what this means and How it affects modification of arrays. You must start a thread before you can read and reply to other threads
- Errors produced when calling 3. Find the maximum element from the BST or4. Find the minimum element from the BST before adding elements so the program should output 0(0) instead of an error "Exception in thread "main" java.lang.NullPointerException: Cannot read field "right" because "<local1>" is null at BST.findMax(BST.java:109) at BST.main(BST.java:194)" "Exception in thread "main" java.lang.NullPointerException: Cannot read field "left" because "<local1>" is null at BST.findMin(BST.java:118) at BST.main(BST.java:197)"Exercise 1: Write a thread class TabPrinter that prints the elements of an array of integers (in one line) every 2 seconds 5 times. Use the way of extending the class thread. Write the main method which creates and starts three threads Printer which will print different arrays of integers. After that it prints "Main won’t wait. Main exits". Modify the above thread program so that you implement the interface Runnable.
