Which code shown below changes the circularly linked list of nodes (with a header/sentinel node)
below:
myFront
Into this singularly lined list (with a header/sentinel node):
myFront →>2|>3]>1>null
In both cases, myFront is a variable of type SLNode referring to a header/sentinel node at the front
of the chain of nodes.
Here is the code which creates the initial condition:
SLNode<Integer> myFront = new SLNode<Integer>(3, null);
myFront = new SLNode<Integer>(2, myFront);
myFront = new SLNode<Integer> (1, myFront);
myFront = new SLNode<Integer>(null, myFront);
myFront.getSuccessor().getSuccessor().getSuccessor().setSuccessor (myFront);
