In C# develop a public function that calculates and returns the average length of a server queue For an MM/1 queue (single server, exponential processing and arrival rates), La while for an M/G/l queue 1-2 Rete (single server, exponential arrival rate and any distribution for processing rate) L. Pis utilization 2(1) of the server (a value 20 and 0). These values should be passed to the function 0 and o, should be optional arguments). Use an enumeration to define the queue type. The function should print an error message and then throw an exception if any of the arguments are out of range
