DSA Patterns for Coding Interviews

Learn the 23 patterns behind most coding-interview problems, one session each. Every pattern starts with a story a child could follow, then a diagram, a step-by-step trace, a reusable Python template, common mistakes and problems to practise. Pair it with the Interview prep tracker.
