leetcodelib
📖 简介
leetcodelib 是一个轻量级的 Python 工具库，旨在解决 LeetCode 刷题时本地输入与题目要求数据结构不一致的痛点。
在 LeetCode 上，题目通常以数组（如 [1, 2, 3]）的形式给出输入，但算法代码却需要处理 链表 (ListNode) 或 二叉树 (TreeNode) 对象。leetcodelib 提供了高效的序列化与反序列化工具，助你在本地 IDE（如 PyCharm, VS Code）中轻松构建测试用例，享受断点调试的便利。
✨ 为什么选择 leetcodelib？
- 🚀 开箱即用：零依赖，纯 Python 实现，安装即用
- 🌳 完美还原：完美支持 LeetCode 的层序遍历（BFS）二叉树格式（含
null处理） - 🔗 链表神器：一行代码实现数组与链表的相互转换
- ⚡ 调试友好：提供将对象转回数组的函数，方便
print验证结果 - 📝 类型提示：完整的 Type Hinting，让 IDE 智能补全更顺畅
- 🧪 测试覆盖：经过大量边界条件测试（空树、单节点、不平衡树）
🚀 快速开始
安装
pip install leetcodelib
一分钟上手
from leetcodelib import *
# 1. 构造输入：将 LeetCode 数组转为二叉树对象
root = build_tree([3, 9, 20, None, None, 15, 7])
# 2. 构造输入：将 LeetCode 数组转为链表对象
root = build_link_list([3, 9, 1, 2])
