: The Multithreaded Cook In this lab, we'll practice multithreading. Using Semaphores for synchronization, implement a multithreaded cook that performs the following recipe, with each task being contained in a single Thread: 1. Task 1: Cut onions. a. Waits for none. b. Signals Task 4 2. Task 2: Mince meat. a. Waits for none b. Signals Task 4 3. Task 3: Slice aubergines. a. Waits for none b. Signals Task 6 4. Task 4: Make sauce. a. Waits for Task 1, and 2 b. Signals Task 6 5. Task 5: Finished Bechamel. a. Waits for none b. Signals Task 7 6. Task 6: Layout the layers. a. Waits for Task 3, and 4 b. Signals Task 7 7. Task 7: Put Bechamel and Cheese. a. Waits for Task 5, and 6 b. Signals Task 9 8. Task 8: Turn on oven. a. Waits for none b. Signals Task 9 9. Task 9: Cook. a. Waits for Task 7, and 8 b. Signals none At the start of each task (once all Semaphores have been acquired), print out a string of the task you are starting, sleep for 2-11 seconds, then print out a string saying that you…
