MUST — Critical Path

12 Tasks • ~25.5h

Non-negotiable core curriculum

DSA (Java) 6 tasks

DSA DP Subsequences II (Knapsack Variants) 5 problems

0/1 Knapsack Problem, Minimum Coins / Coin Change, Target Sum, Coin Change II (unbounded knapsack), Rod Cutting Problem. TUF+ A2Z Step 16.4

3.5h

DSA DP on Strings 4 problems

Longest Common Subsequence (LCS), Print LCS, Longest Common Substring, Edit Distance (Levenshtein Distance). TUF+ A2Z Step 16.5

3.0h

DSA Bipartite Graph Check & Interval Intersections 2 problems LC #785

Check if graph is bipartite using BFS/DFS color array (LC #785), Interval List Intersections (LC #986). Why: bipartite detection appears in graph rounds at Google/Amazon and interval two-pointer intersection is a top-5 most-asked pattern. TUF+ A2Z Step 15.2

1.5h

DSA DSA Transfer: No-Hint Timed DP Subsequences Set 2 problems LC #

Sit 2 unseen DP Subsequences 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.

DSA DSA Transfer: No-Hint Timed DP String Set 2 problems LC #

Sit 2 unseen DP String 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. Ledger checkpoint: ≥ 320 unique problems logged in the Journal (cumulative; tracked metric, Architecture §3).

1.5h

DSA DSA Daily Quota (Week 25) 4 problems

Solve 4 new problems from NeetCode 150 — Greedy; 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.

2.5h
