LeetCode 3603 - Minimum Cost Path with Alternating Directions II
No. The proposed solution does not answer Exercise 4.3.1.1 at all. Exercise 4.3.1.1 asks the reader to study the early history of classical arithmetic algorithms by consulting historical sources (e.g.
Difficulty: 🟡 Medium
Topics: Array, Dynamic Programming, Matrix
Solution
Correctness
No. The proposed solution does not answer Exercise 4.3.1.1 at all.
Exercise 4.3.1.1 asks the reader to study the early history of classical arithmetic algorithms by consulting historical sources (e.g., Sun Tzu, Muhammad ibn Musa al-Khwarizmi, Abu al-Hasan al-Uqlidisi, Fibonacci, and Robert Recorde) and to translate their arithmetic methods into precise algorithmic notation.
The proposed solution discusses a completely different exercise, namely Exercise 4.2.2.30 concerning the numerical evaluation of a function $g(y)$, series expansions, catastrophic cancellation, and pocket calculators. None of this addresses the historical investigation requested by Exercise 4.3.1.1.
Therefore the solution does not answer the question asked.
Gaps and Errors
- Answers the wrong exercise.
Type: Critical error.
The entire submission concerns Exercise 4.2.2.30 and contains no discussion of the historical arithmetic algorithms requested in Exercise 4.3.1.1. 2. No historical sources examined.
Type: Critical error.
The exercise explicitly asks for study of early writings and translation of methods into algorithmic notation. No such material appears. 3. No algorithmic translations.
Type: Critical error.
The required deliverable is a faithful algorithmic formulation of historical arithmetic procedures. None is provided. 4. The "review" evaluates a different proposed solution.
Type: Critical error.
The text judges the correctness of a solution to the calculator exercise rather than evaluating a solution to Exercise 4.3.1.1.
Summary
The submission is entirely unrelated to the stated exercise. It evaluates a solution to a different problem and therefore cannot be considered correct or complete for Exercise 4.3.1.1.
VERDICT: FAIL - the submission answers and evaluates a completely different exercise instead of Exercise 4.3.1.1.
