Write a menu driven program which creates an empty list and gives the following options to the user to perform various operations on the list:
(i) Input an element and a location from the user and insert the element at the entered location in the list.
(ii) Input a location from the user and remove the element from that location in the list. (iii) Input an element from the user and find its location in the list.
(iv) Display the list in sorted order without sorting the list.
(v) Display the list in reverse order without reversing the list.
(vi) Display the list
The program should terminate when the user chooses the option to exit.
