Strengths:

• The solutions are correct and efficient, matching the expected time and space complexities.
• The code is well-organized and easy to follow.
• Comments and variable names are clear and helpful.

Areas for Improvement:

• In Problem1.java, the isSafe method could be slightly optimized by combining the three checks into a single loop, though this is a minor improvement.
• In Problem2.java, the space complexity comment could be more precise by mentioning O(L) for the recursive stack, where L is the length of the word.
• Consider adding more edge case checks (e.g., empty board or word) in Problem2.java, though the current implementation handles them correctly.
