Question

Show that there are more than 2n improper binary trees with n internal nodes such that no pair are isomorphic (see Exercise C-8.33).  Exercise C-8.33  Two ordered trees T′ and T′′ are said to be isomorphic if one of the following holds:    Design an algorithm that tests whether two given ordered trees are isomorphic. What is the running time of your algorithm?

A binary tree with n internal nodes must have n+1leaves and therefore 2n+1 total nodes. so, 
any binary tree with n total nodes is a binary tree with (n−1)/2 internal nodes. 
 Algorithm that tests whether two given ordered trees are isomorphic as listed below:  
int count(int N) {
  if (N
