Question
In a bank, customers wait in a queue (q0) for their turn to complete a transaction. Customers who come first are
served first. At a certain point when there are lots of customers waiting, a decision is taken to split the queue
elements into two empty queues q1 and q2. The customers are split based on the alphabetical order of their first
names. Customers with first name starting A-H are added to q1 while the others (first name starting I-Z) are
added to q2.
In an application, write a method named splitQueue (in an application) that accepts as parameters 3 queues, the
original queue (q0) and two empty queues (q1 and q2) to be filled as described above. Write also a main
method in which you read the first names of customers from the user, fill them into q0 and call the method
splitQueue to split q0 elements into q1 and q2. After the split display the elements of q1 first then those of q2.
The header of the method is:
public static void splitQueue ( Queue q0, Queue q1, Queue q2)
Note: Make sure you do the necessary modifications to allow the queue to store Strings (first names).
