I am not entirely sure what you mean by a "recursive solution". I have
tried cloning the tree by cloning all the nodes in it. However the
problem here is that when I try to clone Node A it has a reference to
Node B as its parent so Node B gets cloned. But when I am cloning Node
B, it has a reference to Node A as its child it goes back to trying to
clone A again.

If you only clone in "one direction", you can avoid this problem. For example, cloning a node Foo wil clone it, and all of its children, but none of its parents.

Alternatively, you could wrap all your nodes in an actual Tree object, and put a clone method on the tree, and not on any of the nodes themselves, and have the tree orchestrating the cloning of the nodes.
