MUST — Critical Path

11 Tasks • ~26.5h

Non-negotiable core curriculum

DSA (Java) 5 tasks

DSA Shortest Path Algorithms 4 problems

Dijkstra's Algorithm (PriorityQueue approach & Set approach), Shortest path in weighted undirected graph. TUF+ A2Z Step 15.3

3.5h

DSA Negative Cycles & All-Pairs Shortest Path 3 problems

Bellman-Ford Algorithm (detect negative cycles), Floyd-Warshall Algorithm (all-pairs shortest path). TUF+ A2Z Step 15.3

3.5h

DSA DSA Transfer: No-Hint Timed Shortest Path Set 2 problems LC #

Sit 2 unseen Shortest Path problems you have never attempted (pick from the LeetCode topic tag, NeetCode “similar questions” or a company list; never a problem named in any learning task), at least 72 h after the learning task — move the set to the first half of next week if needed. Format: 25 min per problem (35 min for a Hard), including 5 min for edge cases and a dry run; no hints, no AI. Pass bar: 2/2 solved inside the time box; on a miss, log the miss reason in the Journal and re-sit a fresh pair within 7 days.

1.5h

DSA OA Simulation (Week 22) 2 problems

90-minute timed OA in HackerRank / CodeSignal / Codility format: 2–3 unseen coding problems from company OA sets + 10 CS/aptitude MCQs, proctor rules (single tab, no AI). Then a 60-minute post-mortem: score = % of test cases passed; log every miss in the Journal. Target from W28: average ≥ 70% of test cases.

2.5h

DSA DP 1D Part III: Interview Classics 4 problems LC #152

Maximum Product Subarray (LC #152), Palindromic Substrings (LC #647), Delete and Earn (LC #740), Combination Sum IV (LC #377). Second DP revisit before DP grids in W24.

2.0h

Competitive Programming 1 tasks

CP Contest & Upsolving (Week 22) LC #

Codeforces Div.2/3 (fortnightly) + LeetCode Weekly Contest + mandatory upsolving. Ratings are tracked metrics, never gates.

2.5h

Core CS (Java) 1 tasks

JAVA Java Collections Internals

Deep dive into HashMap (bucket array, hashing formula, collision resolution, linked list to red-black tree threshold at treeify=8, load factor, rehash), ConcurrentHashMap (segment locking vs synchronized buckets, CAS operations), ArrayList vs LinkedList. Architecture §6.2

3.0h

Cloud & DevOps 1 tasks

DEVOPS Dockerfile, GitHub Actions CI & First Cloud Deploy

Write a multi-stage Dockerfile and a GitHub Actions workflow (build, test, image) that runs on every PR. Deploy the service to a free-tier cloud host and expose a public health URL [VERIFY host terms]. Capstone milestone 6. Why: a deployed, CI-green service is the strongest portfolio signal.

4.0h

Core CS (LLD) 1 tasks

LLD LLD Structural Patterns

Decorator Pattern (Coffee Shop / Pizza), Adapter Pattern, Facade Pattern with compiled Java code.

2.0h

Recruiting Pipeline 1 tasks

PIPELINE Recruiting Pipeline Weekly (Week 22)

Calendar check against the Opportunity Calendar (Architecture §16); send ≥ 5 personalised outreach messages (alumni, seniors, recruiters) and log each in the Tracker; follow up open threads; ask for a referral 1–2 days after any OA invite; apply within 72 h of any new posting on the Target-40.

1.5h

Aptitude 1 tasks

APT Aptitude Timed Drill (Week 22)

25-minute timed mixed set (quant, logical reasoning, data interpretation) from IndiaBix / PrepInsta-style banks; log accuracy and seconds per question in the Tracker. Target: ≥ 70% accuracy by W28.

0.5h

SHOULD — Depth & Mastery

(4 Tasks)

Execute when MUST pace is on track

CORE BPE Tokenizer Build

Build a minimal Byte Pair Encoding tokenizer in Python. (Demoted from MUST to SHOULD per Step 3).

2.5h

CORE Problem-Solving Journal Spaced Review (Week 22)

Re-solve 3 tagged BST and tree problems.

2.0h

APT Quant M22

Probability Advanced & Baye's Theorem.

1.5h

DSA DSA Daily Quota (Week 22)

Solve 4 new problems from NeetCode 150 — Graphs (shortest paths & grids); time-box each at 25 min before any hint (2.5h includes editorial on misses), then log pattern and miss reason in the Journal. Never repeat a problem already in the ledger. [4 problems]

2.5h

STRETCH — If Ahead

(1 Tasks)

Bonus reps & competitive advantage

CORE Train GPT on Custom Text

Fine-tune your from-scratch nanoGPT model on your favorite book or technical documentation.
