The Coin Change (Problem1.py)

Strengths:

• Excellent understanding of dynamic programming concepts
• Comprehensive documentation and comments that explain the algorithm clearly
• Correct use of sentinel value (amount + 1) for "infinity"
• Clean code structure that's easy to follow
• The commented-out recursive solution shows good exploration of different approaches

Areas for Improvement:

• Consider using range(c, amount + 1) to skip the if i < c: continue check, making the loop slightly more efficient
• The commented recursive solution has a bug: case0 and case1 labels are swapped (case0 should be "choose" and case1 should be "not choose")

VERDICT: PASS

House Robber (Problem2.py)

Strengths:

1. Excellent implementation of the DP approach with O(1) space - this is the optimal solution
2. Clear and informative comments that explain the logic and purpose of each variable
3. Proper handling of edge cases prevents potential IndexError
4. Clean variable naming makes the code self-documenting
5. The solution significantly outperforms the reference solution in both time and space

Areas for Minor Improvement:

1. The edge case if n <= 2: return max(nums) if nums else 0 could be simplified since constraints guarantee n >= 1, but this is a minor stylistic point
2. Consider adding a brief docstring at the class level for completeness

The solution demonstrates a solid understanding of dynamic programming and is production-ready.

VERDICT: PASS
