Coin Change (CoinChange.java)

EVERAGE SCORE: [0-10] based on correctness, time complexity, space complexity, time/space complexity vs reference, code quality, and efficiency. Provide a O( unbounded ) score based on(unbounded) means there is no ceiling for the number of attempts to solve the problem and the student can keep trying until they solve it correctly.

House Robber (HouseRobber.java)

Strengths:

• Excellent use of dynamic programming to achieve O(n) time complexity, which is the optimal solution.
• Proper handling of edge cases (empty array, single element).
• Clear comments explaining the approach.
• Well-structured and readable code.

Areas for improvement:

• The space complexity could be reduced from O(n) to O(1) by using two variables instead of a dp array, since we only need the previous two values at any point.
• The class name should ideally be "Solution" to match common LeetCode conventions, though this is a minor stylistic point.
• Consider adding a brief explanation of the recurrence relation in comments for educational purposes.

VERDICT: PASS
