• Strengths:

  • Both solutions correctly implement dynamic programming and handle edge cases well.
  • The code is well-commented and easy to understand.
  • The time complexity improvements over the reference solutions are excellent.

• Areas for Improvement:

  • For coinChange, consider optimizing the space complexity by using a 1D DP array. This would reduce the space complexity from O(m*n) to O(n).
  • For rob, consider optimizing the space complexity by using variables to store only the last two values instead of the entire DP array. This would reduce the space complexity from O(n) to O(1).
  • Ensure consistency in coding style (e.g., using semicolons or not) throughout the code.

• Strengths:

  • Both solutions correctly implement dynamic programming and handle edge cases well.
  • The code is clean, readable, and well-commented, making it easy to understand.
  • The time complexity improvements over the reference solutions are excellent.

• Areas for Improvement:

  • For the coinChange problem, consider optimizing the space complexity by using a 1D DP array instead of a 2D array. This would reduce the space complexity to O(n).
  • For the rob problem, consider further optimizing the space complexity to O(1) by only keeping track of the last two values instead of the entire DP array.
  • While the comments are helpful, ensure they are concise and directly relevant to the code.
