Assume you are using the text's array-based queue and have just instantiated a queue of capacity 10. You enqueue 5 elements, dequeue 4 elements, and then enqueue 7 more elements. Which indices of the internal array elements hold the value null, that is, do not hold an element?

Consider a two-server queue with Exponential arrival rate λ. Suppose servers 1 and 2 have exponential rates μ1 and μ2, with μ1 > μ2. If server 1 becomes idle, then the customer being served by server 2 switches to server 1. a) Identify a condition on λ,μ1,μ2 for this system to be stable, i.e., the queue does not grow indefinitely long. b) Under that condition, and the long-run proportion of time that server 2 is busy.
