A "service" transaction results in a print request being removed from the priority queue and the customer name being displayed on the console. A transaction containing the string "end-of-file" will signal the end of the input. Your program will display the number of print requests remaining in the queue when the "end-of-file" transaction is processed. Sample input transactions and output expected using a priority queue: 2-01-guo 1-02-hannie 3-03-ian service (output: 1-02-hannie) service (output: 2-01-guo) 1-04-danny 3-05-eli 1-06-fan service (output: 1-04-danny) service (output: 1-06-fan) end-of-file (output: There are 2 remaining print requests in the queue.)
