Consider the linearization points of the enq ()and deq()methods of the lock-free queue (Figs.10.11and 10.12).

1.Can we choose the point at which the returned value is read from a node as the linearization point of a successful deq ()? Explain.

2.Can we choose the linearization point of the enq ()method to be the point at which the tail field is updated, possibly by other threads? Explain.
