A four-week coding plan that builds transfer
Work through 20 selected LeetCode exercises with invariants, small traces, review prompts, and a plan for correcting recurring mistakes.
What you will learn
- Sequence patterns instead of randomly accumulating problems.
- Explain why an approach works and how much it costs.
- Separate a successful retry from a fresh transfer check.
