Strengths:

• The student has demonstrated a strong understanding of dynamic programming and has applied it effectively to solve both problems.
• The code is clean, well-commented, and follows best practices.
• The student has optimized both time and space complexity, showing a good grasp of algorithmic efficiency.

Areas for Improvement:

• While the comments are helpful, they could be slightly more detailed to explain the intuition behind the dynamic programming approach, especially for the coinChange problem.
• The student could consider adding edge case checks (e.g., empty coins array or negative amount) to make the code more robust, although the current implementation handles these cases implicitly.

The student has done an excellent job in both problems. The solutions are correct, efficient, and well-commented. The use of dynamic programming in the coinChange problem and the space optimization in the rob problem are particularly commendable. One minor suggestion for the coinChange problem is to consider sorting the coins in descending order and breaking early if the remaining amount becomes zero, but this is optional and not a requirement for a correct solution. Overall, the student's understanding of dynamic programming and space optimization is evident.
