Strengths:

• The student demonstrates a strong understanding of dynamic programming concepts, including recursion, memoization, and tabulation.
• The code is well-organized and easy to follow, with clear comments explaining each approach.
• The student provides multiple solutions, showing a thorough exploration of the problem space.
• The student correctly identifies and optimizes time and space complexities.

Areas for Improvement:

• In the recursive solution for Leetcode_256, the student could add a comment explaining why the base case returns 0 when i == costs.length. This would make the logic clearer for readers.
• For Leetcode_518, the student could consider adding a brief explanation of why the tabulation approach works, especially the logic behind the dp[i][j] = dp[i-1][j] + dp[i][j-coins[i-1]] line.
• The student could also consider adding edge case handling comments, such as what happens when the input array is empty or the amount is 0.
