• Strengths:
  • The student has implemented both memoization and tabulation approaches for the coin change problem, showing a good understanding of dynamic programming.
  • The house robber solution is well-optimized and follows best practices.
  • The code is generally readable and well-structured.
• Areas for Improvement:
  • The memoization solution for coin change has a logical error in the memoization check. The dp[idx][t] check should be at the beginning of the function to avoid redundant calculations.
  • The tabulation solution is correct but commented out. It would be better to uncomment and use it or remove it if not needed.
  • The memoization solution could be improved by initializing the dp array with a more appropriate value (e.g., Integer.MAX_VALUE) to avoid confusion with the -1 check.
