1. Draw a picture of the linked structure created by this code fragment. You must show which nodes the named variables
(P, Q, R) refer to.
[5]
Node P= new Node (43), Q = new Node (31), R = new Node (52);
P.next = Q; Q.next
= R; R. next = P;
2. Given the linked structure from the previous question, show the values of the following expressions. If an expression
is invalid (syntax error), write “Invalid” for its value. If evaluating an expression would result in an Exception, write
“Exception” for its value.
Note: An expression’s value could be the same as that of a variable. In that case you should write the variable name
for the value (if the value itself cannot be determined from the information you have).
Expression
Q. data
P. next next. data
R.next.data
R. data.next
Q.next.next
