How hello-algorithm is put together
This is a Chinese-language educational repository ('hello-algorithm') containing algorithm/data-structure learning notes, interview preparation material, and e-book archives — not an application. Content is organized into four top-level parts (PART_1_算法基础 fundamentals, PART_2_力扣图解 LeetCode illustrated solutions, PART_3_大厂面试 company interview archives, PART_4_CS知识汇总) plus '算法读物' reading materials and 'other' topic notes. The only executable code observed is standalone Java Solution classes implementing 剑指offer (Coding Interviews) problems, each self-contained with no build system or framework. There is no runtime, data flow between components, datastore, or deployment infrastructure; the deliverable is static documentation (Markdown, PDF, ZIP, DOC/PPT).
Languages
Major components
PART_1_算法基础
Algorithm and data-structure foundations: a knowledge-framework PDF plus per-topic README notes (linked list, stack, queue, hash table, heap, tree, trie, graph, priority queue, doubly linked list).
PART_2_力扣图解
Illustrated LeetCode-style problem walkthroughs organized by category (arrays, linked lists, dynamic programming, bit manipulation, binary search, backtracking, sorting, supplementary problems) as numbered Markdown files, plus a compiled PDF edition.
PART_3_大厂面试
Big-company (Chinese tech firm) interview question archives packaged as ZIP files per company (Alibaba, Tencent, Baidu, JD, Huawei, ByteDance/Toutiao, Didi, Meituan).
算法读物/剑指offer
Sword-Point-Offer coding solutions: Java Solution classes for individual problems (e.g., binary search for value==index, XOR-based single-number problems) alongside the reference PDF.
算法读物/设计模式 & other/designpattern
GoF design-pattern write-ups in Chinese, one Markdown file per pattern (singleton, factory, observer, decorator, etc.), duplicated in two directories.
算法读物/计算机网络 & other/netword
Layer-by-layer computer-networking study notes (overview, physical, link, network, transport, application layers), duplicated across two directories.
算法读物/操作系统 & other/os
Operating-system concept notes covering memory management, processes, deadlock, disk scheduling, and page-replacement algorithms.
千本开源电子书 / 百张思维导图
Curated lists of open-source books (including python_100.md) and mind-map collections distributed as README/image assets.
