1. The code part (60%)

a. Use the public class NodeSequence to implement Sequence (Sequence was presented in class).

b. Provide the Bubble sort code using the Sequence. // O(n^2)

c. Provide the Merge sort code using the Sequence. // O(nlog n)

d. In the main function, randomly generate a large sequence containing random integers (over 20,000),

and use the two sorts to sort the Sequence and compare the efficiency by a clock.

(Hint: You should have one class like

public class NodeSequence extends NodePositionList implements Sequence )...

This is a Java Program...
