Work through at least 50 algorithm and data structure problems using a structured approach: for each problem, attempt a solution independently before looking at hints, then write a solution explanation (not just code) that covers time complexity, space complexity, and why this approach works. Cover at minimum: arrays, hash maps, trees, graphs, dynamic programming, and sorting. Use the Neetcode 150 roadmap or equivalent as your guide.
Proof required
Submit: a document or repository listing 50 solved problems with the problem name, your solution code, and a 2–3 sentence complexity analysis for each; and a 200-word reflection naming the category that was hardest and why, and one pattern you now recognise automatically that you did not before.
What gets checked
- 50 problems are listed with real solution code — not links to accepted submissions, not pseudocode, but actual runnable code
- Complexity analysis is present for each: O(n) or O(n log n) with a brief explanation of why, not just a label
- Reflection names a specific pattern (e.g. sliding window, two pointers, DFS template) and explains how recognising it now changes how the submitter approaches a new problem
