Data Structures and Algorithms Track

This track integrates the educational chapters from dsa_book_2 into the placement-preparation book. It is a complete path from mathematical and complexity foundations through core data structures, graph algorithms, dynamic programming, problem-solving patterns, interview communication, and advanced algorithms.

The existing coding interview section remains the concise placement companion. Use this track when you need the proof, implementation details, variants, or a structured study plan behind a pattern.

30-day interview path

Read complexity, arrays and strings, sorting, binary search, hashing, recursion/backtracking, trees/BSTs, heaps, DFS/BFS, dynamic programming, two pointers, sliding window, and the problem-solving chapter. Practise after each chapter; do not treat reading as a substitute for implementation.

60–90-day fundamentals path

Follow Parts I–VII in order, then use the interview-preparation chapters and the appendices. Revisit a topic by starting at its chapter in the Summary and following its local cross-references.

Advanced path

Parts XII–XX cover persistent and probabilistic structures, advanced graph and DP techniques, string algorithms, cache-aware engineering, randomized algorithms, optimization, and graduate-level topics. These are valuable for specialist interviews, but should come after the core patterns are fluent.

A repeatable problem-solving loop

  1. Restate the input, output, constraints, and edge cases.
  2. Write a brute-force baseline and its complexity.
  3. Match the constraints to a pattern or data structure.
  4. State the invariant or proof idea before coding.
  5. Implement with explicit ownership, bounds, and overflow decisions.
  6. Dry-run normal, boundary, duplicate, and adversarial inputs.
  7. Compare time and space against the baseline and explain trade-offs aloud.

Integration notes

Only the source repository’s educational Markdown was copied. Its repository metadata, CI/deployment files, generated output, and unusual anchor-named artifacts were excluded. Chapter navigation was adapted into the parent book’s SUMMARY.md; stale source-relative links were repaired or converted to explanatory text. This keeps the track usable as one book instead of a nested Git repository.
