如何在二叉搜索树中搜索值？
def search(node, target): if node is None: return None elif node.data == target: return node elif target < node.data: return search(node.@(4), target) else: return search(node.@(5), target)
def search(node, target): if node is None: return None elif node.data == target: return node elif target < node.data: return search(node.left, target) else: return search(node.right, target)
