Binary trees can be used to represent the decision-making process of computer-controlled characters in games, such as in decision trees. 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.
