Strengths:

• The student demonstrates a strong understanding of different algorithmic approaches (recursion, memoization, tabulation, and space optimization).
• The code is well-commented and organized, making it easy to follow.
• The student provides multiple solutions for the knapsack problem, showing depth of knowledge.

Areas for Improvement:

• For the twoSum problem, while the solution is correct and efficient, it would be good to mention that the problem guarantees exactly one solution, which is why the return statement at the end is safe.
• The knapsack problem solutions could benefit from a brief explanation of why the 1D optimization works (i.e., iterating backwards to avoid overwriting values needed for subsequent calculations).
