创建随机节点的二叉树类，中断

import random

class TreeNode:
    def __init__(self, value):
        self.value = value
        self.left = None
        self.right = None

class RandomBinaryTree:
    def __init__(self):
        self.root = None

    def add_node(self, value):
        if random.random() < 0.1:  # 假设当随机数小于0.1时中断构建
            raise Exception("Build process interrupted randomly.")
        if not self.root:
            self.root = TreeNode(value)
        else:
            self._add_node_recursive(self.root, value)

    def _add_node_recursive(self, current_node, value):
        if value < current_node.value:
            if current_node.left is None:
                current_node.left = TreeNode(value)
            else:
                self._add_node_recursive(current_node.left, value)
        else:
            if current_node.right is None:
                current_node.right = TreeNode(value)
            else:
                self._add_node_recursive(current_node.right, value)

# 使用示例
try:
    tree = RandomBinaryTree()
    for i in range(10):
        tree.add_node(random.randint(1, 100))
except Exception as e:
    print(e)
