9. A binary tree is symmetric if for every internal node the number of nodes in its left subtree is the same as the number of nodes in its right subtree.

![9. A binary tree is symmetric if for every internal node the number of nodes in its left
subtree is the same as the number of nodes in its right subtree. Given a node p, let
p.size() return the number of nodes in the subtree with root p, and p.getLeftChild()
and p.getRight Child() return the left and right children of p, respectively. Write a
recursive algorithm public boolean isSymmetric (Binary TreeNode<T> r) that receives
as parameter the root r of a binary tree and it returns true if the tree is symmetric and
it returns false otherwise. For example for the tree below with root r the algorithm
must return true, but for the tree with root s it must return false.
