Strengths:

• Both solutions are correct and efficiently implemented.
• The code is well-commented and easy to understand.
• The WordSearch.java solution includes smart optimizations (search pruning) that improve performance.
• The time and space complexity analyses are accurate and well-explained.

Areas for Improvement:

• In NQueens.java, the method isSafe could be slightly optimized by combining the row check and diagonal checks into a single loop, though the current implementation is already clear and correct.
• In WordSearch.java, the search pruning logic (checking first and last character occurrences) is a great optimization, but it might be worth mentioning that this is an optional enhancement and not strictly necessary for correctness.
