Given the following definition of the TreeNode struct and data member of the BinarySearchTree class: struct TreeNode { unsigned value; // data field TreeNode left; // to hold the address of the left child TreeNode *right; // to hold the address of the right child }; class BinarySearch Tree { private: TreeNode *root_; // Pointer to the root node In the following space, implement the public facing count method and its private recursive count helper function of the BinarySearch Tree class to return the number of nodes in the tree. It is important that the function header reflects the fact that counting nodes shall not affect the content of the invoking tree. These functions are to be saved in the BinarySearch Tree.cpp file.

Programming language C++ problem

Given the following definition of the TreeNode struct and data member of the
Binary Search Tree class:
struct TreeNode {
unsigned value; // data field
TreeNode *left;
// to hold the address of the left child
TreeNode *right; // to hold the address of the right child
};
class BinarySearchTree {
private:
TreeNode *root_; // Pointer to the root node
In the following space, implement the public facing count method and its private recursive
count helper function of the BinarySearch Tree class to return the number of nodes in the tree. It
is important that the function header reflects the fact that counting nodes shall not affect the
content of the invoking tree. These functions are to be saved in the BinarySearch Tree.cpp file.
