21 days. 63+ algorithms. Mission accomplished. Completion Date: July 6, 2025
You've mastered essential computer science fundamentals from basic data structures to intermediate problem-solving techniques.
- Foundation in problem solving and algorithmic thinking
- Code implementation and debugging skills
- Introduction to complexity analysis
- Basic technical interview preparation
21 Days of Code was just a warmup!
This challenge served as your introduction to competitive programming and algorithmic thinking. You've built a solid foundation, but the real journey is just beginning.
Get ready for the next challenge: 100 Days of Code!
The upcoming 100 DoC will dive deeper into advanced topics including:
- Advanced Data Structures (Trees, Graphs, Heaps)
- Complex Algorithms (Dynamic Programming, Advanced Graph Algorithms)
- Optimization Techniques and Advanced Problem Solving
- Comprehensive Technical Interview Preparation
- Review and practice the concepts from 21 DoC
- Prepare mentally for the intensive 100 Days of Code challenge
- Start thinking about more complex algorithmic problems
Your dedication during these 21 days laid the groundwork for greater challenges ahead. The community collaboration and consistent effort created a strong foundation for everyone.
