Strengths:

• The student has implemented both solutions correctly and efficiently.
• The code is clean, readable, and follows good practices.
• The logic is well-organized and easy to understand.

Areas for Improvement:

• In the N-Queens solution, the issafe method could be slightly optimized by combining the three while loops into a single loop that checks all three directions in one pass, though this would not change the asymptotic complexity.
• In the word search solution, the dfs method could be made more concise by directly returning the result of the recursive calls without using an intermediate variable r and c.
