Strengths:

• The student has demonstrated a good understanding of dynamic programming concepts.
• The solutions are well-commented and easy to follow.
• The House Robber solution is optimally implemented in terms of both time and space complexity.

Areas for Improvement:

• For the coin change problem, consider optimizing the space complexity by using a 1D array instead of a 2D array. This would reduce the space complexity from O(m*n) to O(n).
• The comment "filling first column with infinity" is slightly misleading since the code actually fills the first row (not column) with a large value (amount+1). Ensure comments accurately reflect the code.
• The initialization of the DP table could be made clearer by explicitly stating why amount+1 is used (as a stand-in for infinity).
