create a linked list with vowels. Add the elements “P, A, T prefixed to the list and 7 at end of the list. Update and display the list by adding by adding a new element indexed at 6 with T1. Remove the element “A” from the updated list and display the length of the list.

linkedList.addToTail('a');
linkedList.addToTail('e');
linkedList.addToTail('i');
linkedList.addToTail('o');
linkedList.addToTail('u');

linkedList.addToHead('P');
linkedList.addToHead('A');
linkedList.addToHead('T');
linkedList.addToTail('7');

linkedList.insertAt(6, 'T1');
linkedList.remove('A');

System.out.println(linkedList.getSize());
