How can I solve binary tree problems in Python?

You can solve binary tree problems in Python by using recursion or iterative methods. What specific problem do you have in mind?

I'm trying to implement a function to find the height of a binary tree.

To find the height of a binary tree, you can use a recursive function that calculates the height of the left and right subtrees.

Can you show me an example of that?

Sure! Here's a simple implementation:

def height(node):
    if node is None:
        return -1
    else:
        left_height = height(node.left)
        right_height = height(node.right)
        return 1 + max(left_height, right_height)

What if I want to find the diameter of the binary tree?

The diameter can be found using a similar approach. You can calculate the height of the left and right subtrees and keep track of the maximum diameter found during the traversal.
