Website introduction
LeetCode is the world’s largest programming interview question-brushing platform, providing 3,000+ algorithm and data structure questions. It is a standard preparation tool for technical interviews at Internet companies.
In the era of AI-assisted programming, algorithmic thinking remains the core competitiveness of top engineers. AI can help you write business code, but the algorithmic ability and system design ability in the interview cannot be replaced by AI. LeetCode helps you develop these core abilities.
Core learning content
- data structure: Array, linked list, stack, queue, tree, graph, hash table
- algorithm: Sorting, search, dynamic programming, greedy, backtracking, divide and conquer
- Database question: SQL Query Exercise
- System design: Large system architecture interview questions
- competition: Weekly programming competition to improve algorithm speed
Why recommended
The original LeetCode question or a variation is almost mandatory for interviews at Internet companies. The Chinese version (Lekou) has a complete problem solving community and learning plan. It is classified according to difficulty and theme to make solving problems more directional. Even with AI programming assistants, the ability to solve complex algorithmic problems is still what distinguishes good engineers.
Suitable for whom
- Job seekers preparing for technical interviews with Internet companies
- Developers who want to improve their algorithm and logical thinking skills
- Competitors in programming competitions
