Write a method count that accepts an element value as a parameter and returns the number of occurrences of that value in the list.
For example, suppose a variable named list stores the following sequence of elements:
[one, two, three, two, four, two, five, two, two, six]
A call of list.count("two") should return 5 because there are five occurrences of that value in the list.
If the list does not contain the value at all, return 0.
The example shown is a list of strings, but this is a generic linked list class that can store any type of objects.
Assume that you are adding this method to the LinkedList<E> class as defined below:
public class LinkedList<E> {
private ListNode front; // null for an empty list
...
}
