Question

We want the program to use a DEQueue object to create a sorted list of names. The program gives a user the following three options to choose from – insert, delete, and quit. If the user selects ‘insert’, the program should
accept a name (String type) from the user and insert it into the deque in a sorted manner. If the
user selects ‘delete’, the program should accept a name (String type) from the user and delete
that name from the deque. Display the contents of deque after each insert/delete operation. The
program continues to prompt the user for options until the user chooses to quit. You have to
implement the insert and delete operations.
