The tree/node could have more operations added into it

[Vladifish]

Notable ones:

BT

---

• isLeaf
• isEmpty
• isInnerNode

BTNode

---

• setLeft
• setRight

[Vladifish]

Set left and set right might be redundant imo. isInnerNode could also be slightly problematic

Apparently isInnerNode isnt super complicated lol

// Implemented in tree
boolean isInnerNode(BTNode n) {
	if(n == null) // prevents NPE
		return false;
	if(n.left == null && n.right == null) // isLeaf
		return false;
	if(n == root)
		return false;
	return true;
}
