Count the Nodes

This IntList stores no counter, so size() has to find out the hard way: start a cursor at head and follow next until it runs off the end, counting as it goes.

Requirements:
1. size() returns the number of nodes currently in the list.
2. An empty list returns 0.

The Node class is provided - do not rename it and do not add public to it, because a Java source file may contain only one public class.

Do NOT write a main method.

Expected Output:

0↵
3↵
4↵
5 -> 10 -> 20 -> 30 -> null↵

= newline. The output ends with a newline — print one after the last line.
