Question

In this lab, you will add four methods to the LinkedIntList class

that we developed in class. The method signatures are:
public int peek(); public void exchange(); public int minElement(); public int maxElement(); The peek() method returns the data in the first node without modifying the list in any way. For example, if the list was
10 -> 20 -> 30 -> null Then peek() should return 10, leaving the list unchanged.
The exchange() method exchanges the values in the first two nodes. For example, if the list was
10 -> 20 -> 30 -> null before the call to exchange(), then afterward it looks like this:
20 -> 10 -> 30 -> null The minElement() and maxElement() methods return (respectively) the minimum and maximum element of the list.
