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.

Consider the recursive definition of full binary tree as,
\( B_{1} \cdot \) The empty tree is a binary tree.
\( B_{2} \). A s

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.

Consider the recursive definition of full binary tree as, The empty tree is a binary tree. . A single vertex is a binary tree and in this case, the vertex is the root of the tree. . If and are binary trees with roots and respectively, then the following tree is a binary tree with root . Modify the definition by deleting part , that is an empty tree is not a binary tree. A tree that satisfies the modified definition is called a full binary tree. (a) An example of a full binary tree with five nodes and root is shown below.

(a) To prove that a full binary tree has an odd number of nodes, we will use structural induction.

Base case: The smallest full binary tree is a single node. It has one node, which is an odd number.

Inductive step: Assume that a full binary tree with n nodes has an odd number of nodes. We want to prove that a full binary tree with n+1 nodes also has an odd number of nodes.
