Explain the difference between a 2-node and a 3-node.

What will be an ideal response?

The terms 2-node and 2-node describe nodes in a 2-3 tree. A 2-node is a node that has a single element and
has 0 or 2 children. It is most like a node in a binary tree, except that it cannot have a single child node. A 3-node is a node has
2 elements and 0 or 3 children.
