Modify the following  C program to synchronize between threads using semaphore Run and test the codes before and after the modification.   #include #include #include sem_t sync; int  x = 0; void* thread(void* arg) {      x = x + 1;    printf("The Value of x is %d\n", x);         } main() {    sem_init(&sync, 0, 0)    pthread_t th1,th2;    pthread_create(&th1,NULL,thread,NULL);    pthread_create(&th2,NULL,thread,NULL);    pthread_join(th1,NULL);    pthread_join(th2,NULL);     }

// This program is synchronized class Callme { Exercise2: Find and correct the errors from the following program and then compile it. After compilation run the program and write the output in the box bellow. synchronized void (String msg) { System.out.print("[" + msg); Code: try { Thread.sleep(); } } catch (InterruptedException e) { System.out.println("Interrupted"); } System.out.print("]"); } class Caller implements Runnable { String msg; Callme target; Thread t; public Caller (Callme targ, String s) { target= targ; msg=s; } t = new Thread(this); t.start()); public void run () { target.call(msg); } } class Synch { public static void main (String args[]) { Callme target= new Callme(); Caller obl= new Caller (target, "Hello"); Caller ob2 Caller ob3 try { obl..join(); ob2..join(); ob3..join(); }catch (InterruptedException e) { System.out.println("Interrupted"); } } new Caller (target, "Synchronized"); new Caller (target, "World"); }

USE PYTHON MULTI THREADING TO COMPLETE DO NOT USE PROCESSES  ONLY COMPLETE PART 2 using MULTI THREADING 1) 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). ************ONLY COMPLETE THIS PART BELOW*************** 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 thread and the parent thread aggregates and returns the total to its parent thread. Start with 7 nodes thread tree, when you are comfortable, you can extend it to a full…

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…
