Part1
Modify the author's "MyLinkedList" class to add the following methods:
a. swap
receives two index positions as parameters, and swaps the nodes at these positions by changing the links, provided both positions are
within the current size
b. shift
receives an integer (positive or negative) and shifts the list this many positions forward (if positive) or backward (if negative).
1,2,3,4 shifted +2 3,4,1,2
1,2,3,4 shifted -1 4,1,2,3
c. erase
receives an index position and number of elements as parameters, and removes elements beginning at the index position for the number of elements specified, provided the index position is within the size and together with the number of elements does not exceed the size
d. insertList
receives another MyLinkedList and an index position as parameters, and copies the list from the passed list into the list at the specified
position, provided the index position does not exceed the size.
e. main
add code to the main method to demonstrate each of your methods
Part 2
Create a MyStack class that uses an ArrayList to make a stack.
Use your MyStack class to demonstrate the nested symbol algorithm seen on slide 35 of the chapter 3 slides.
