Below, write a Linked Chain method that will return reference to the middle node. If the Linked Chain has an even number of nodes the "middle node" should be closer to the back.
For example, if the linked chain looked like this:
1
A --> B --> C --> D
where firstNode referenced the node containing A, this method would return the node containing C
If the linked chain looked like this:
1
A --> B --> C --> D --> E
where firstNode referenced the node containing A, this method would return the node containing C
