Question 1:

Consider the following Bakery lock. It has been initialized for five threads, with threadIDs 0, 1, 2, 3 and 4.

Initially, the Label array is {0, 0, 0, 0, 0}.

The flag array is {false, false, false, false, false}.

No thread has entered the lock method.

Then, thread 3 enters the lock method, and completes through line 15.

Blank 1: What are the contents of the label array? Use the same format as shown above.

Blank 2: What are the contents of the flag array? Use the same format as shown above.
