Strengths:

• The N-Queens solution is correct and follows the standard backtracking approach.
• The code is well-organized with helper functions for clarity.
• The isSafe function correctly checks the column and both diagonals.

Areas for Improvement:

• In the helper function for N-Queens, the parameter 'j' is unnecessary since it is not used. You can remove it and define j only in the inner loop.
• Consider using a list of strings or a 1D array to represent the board to save space, but for n up to 9, the current approach is acceptable.
• For the Word Search solution (if you want to improve), you can avoid the base case for a 1x1 board by handling it within the DFS. The current special case might not be necessary because the DFS should handle it.

Overall, both solutions are well-written and efficient.
