Algorithm-Fundamentals

算法基本功学习仓库:LeetCode 题解、ICPC 模板、面试/笔试复习材料。

结构(2026-08 重构):全部题目按算法类型组织为一级目录,共 244 个题目文件;知识笔记入 notes/,图片资源入 assets/。

题目分类(一级目录)

目录 题目数
misc/ 50
math/ 22
python-basics/ 21
dynamic-programming/ 20
binary-search/ 17
tree/ 11
graph/ 10
linked-list/ 10
prefix-sum/ 9
two-pointers/ 9
binary-indexed-tree/ 8
backtracking/ 7
string/ 7
greedy/ 6
sliding-window/ 6
hash/ 5
sorting/ 5
bit-manipulation/ 4
heap/ 4
trie/ 4
stack/ 3
matrix/ 2
simulation/ 2
leetcode/ 1
union-find/ 1

每个 .ipynb 首个 cell 为标准题面(自动抓取自 leetcode.cn 或按笔记合成),后续为个人笔记与题解。

其他目录

  • notes/ —— 知识笔记(Transformer/GRPO/RL/概率论/面试八股等)
  • assets/ —— 图片与资源
  • tools/classify.py —— 题目整理工具:新题丢入根目录后运行自动分类 + 补题面
python3 tools/classify.py               # 分类新题 + 补题面
python3 tools/classify.py --fetch-only  # 只补题面
  • 2025 New Plan. Go! Go! Go!
