Write the recursive function count; it is passed balanced binary (any binary tree, not necessarily a binary search tree) and a value as arguments. It returns the number of times the values is in the tree. In the binary tree below, count(tree,1) returns 1, count(tree,2) returns 2, count(tree,3) returns 4.

Python code:

def max_depth_util(root, val, level):

if root is None:

return 0;

if root.data == val:

return level

if root.left is not None or root.right is not None:

return max_depth_util(root.left, val, level + 1) + max_depth_util(root.right, val, level + 1)

return 0;

def max_depth(root,val):

return max_depth_util(root,val, 1)
