WebJan 12, 2024 · Binary trees are really just a pointer to a root node that in turn connects to each child node, so we’ll run with that idea. First, we create a constructor: class BSTNode: def __init__(self, val=None): self.left = None self.right = None self.val = val. We’ll allow a value, which will also act as the key, to be provided. WebGiven a binary search tree (BST), convert it into a height-balanced binary search tree. For a height-balanced binary search tree, the difference between the height of the left and right subtree of every node is never more than 1. The height of a binary search tree with n nodes is never more than log 2 (n) + 1.
