Refer to following Exercise for the definition of a full binary tree.
Exercise : In Example 3.22, we gave a recursive definition of a binary tree. Suppose we modify this definition by deleting part B1, so that an empty tree is not a binary tree. A tree satisfying this revised definition is called a full binary tree.
now please answer the following questions:
(a) Use structural induction to prove that a full binary tree has an odd number of nodes.
(b) Prove that a full binary tree has an even number of edges.
