Exercise 125. Consider the unbounded queue implementation shown in Fig. 10.21.This queue is blocking, meaning that the deq() method does not return until ithas found an item to dequeue.
The queue has two fields: items is a very large array, and tail is the index ofthe next unused element in the array.1. Are the enq() and deq() methods wait-free? If not, are they lock-free? Explain.2. Identify the linearization points for enq() and deq(). (Careful! They may beexecution-dependent.)
