BJP4 Exercise 16.10: stretch

Related Links:
Author: Marty Stepp (on 2016/09/08)

Write a method stretch that takes an integer n as a parameter and that increases a list of integers by a factor of n by replacing each integer in the original list with n copies of that integer. For example, if a variable called list stores this sequence of values: 

[18, 7, 4, 24, 11]

And we make the following call: 

list.stretch(3);

The list should store the following values after the method is called: 

[18, 18, 18, 7, 7, 7, 4, 4, 4, 24, 24, 24, 11, 11, 11]

If the value of n is less than or equal to 0, the list should be empty after the call.

Assume that you are adding this method to the LinkedIntList class as defined below: 

public class LinkedIntList {
    private ListNode front;   // null for an empty list
    ...
    
    // your code goes here
}
