- * Barlas Chpt 3 Ex 12:
-    Create three threads, each printing out the letters A, B, and C.
-    The printing must adhere to these rules:
-        • The total number of Bs and Cs that have been output at any
-          point in the output string cannot exceed the total number
-          of As that have been output at that point.
-        • After a C has been output, another C cannot be output until
-          one or more Bs have been output.
-    Use semaphores to solve the problem.
