A collection of LeetCode algorithm templates and cheatsheets (binary search, two pointers, BFS/DFS, trees, etc.) in Java and Python, created by a Peking University alumnus for coding interview prep. It is primarily a study resource with PDFs and example code, promoting LintCode and a paid course.

Use cases

• prepare for coding interviews at big tech companies
• learn common algorithm templates for leetcode
• review data structures like binary trees and hash tables before an interview
• find high-frequency interview problems to practice
• memorize reusable code templates for BFS and DFS

When to choose

• you are preparing for algorithm-heavy technical interviews
• you want concise, reusable templates for common LeetCode patterns
• you prefer structured study material with curated high-frequency problems

When to avoid

• you need a production-ready algorithm library to import into your project
• you want actively maintained code with tests and releases
• you dislike promotional content tied to paid courses
