while True: VARS[var.strip()] = val.strip() print eval(line) var, val = line.strip().split("=") import sys line = sys.stdin.readline() for key in VARS: line = line.replace(key, VARS[key]) line = sys.stdin.readline().strip() while True: VARS = {} if line.strip() == '%%%': break 重排一下代码

以下是重排后的代码：

import sys

VARS = {}

while True:
    line = sys.stdin.readline().strip()
    if line.strip() == '%%%':
        break
    var, val = line.strip().split("=")
    VARS[var.strip()] = val.strip()
    for key in VARS:
        line = line.replace(key, VARS[key])
    print(eval(line))

VARS = {}

重排后，代码结构更加清晰，更易于阅读和理解。同时，也能更好地体现代码的逻辑和执行顺序。

对下面代码每一步含义进行注释 def insert(self, val): if not self.root: self.root = TreeNode(val) return cur = self.root while cur: if val < cur.val: if not cur.left: cur.left = TreeNode(val) return else: cur = cur.left else: if not cur.right: cur.right = TreeNode(val) return else: cur = cur.right

这段代码是二叉搜索树的插入操作代码，具体注释如下：

def insert(self, val):  # 定义插入操作函数，val为要插入的节点值
    if not self.root:  # 如果二叉搜索树为空，则将要插入的节点作为根节点
        self.root = TreeNode(val)  # 创建根节点
        return  # 返回
    cur = self.root  # 如果二叉搜索树不为空，则从根节点开始查找
    while cur:  # 进入循环，直到找到合适的插入位置或者查找到叶子节点
        if val < cur.val:  # 如果要插入的值小于当前节点值
            if not cur.left:  # 如果当前节点的左子节点为空，则将要插入的节点作为当前节点的左子节点
                cur.left = TreeNode(val)  # 创建左子节点
                return  # 返回
            else:  # 如果当前节点的左子节点不为空，则继续向左查找
                cur = cur.left  # 将当前节点设置为左子节点，继续查找
        else:  # 如果要插入的值大于等于当前节点值
            if not cur.right:  # 如果当前节点的右子节点为空，则将要插入的节点作为当前节点的右子节点
                cur.right = TreeNode(val)  # 创建右子节点
                return  # 返回
            else:  # 如果当前节点的右子节点不为空，则继续向右查找
                cur = cur.right  # 将当前节点设置为右子节点，继续查找

总体来说，这段代码的作用是将一个节点插入到二叉搜索树中，并保证插入后仍然是二叉搜索树。
