• For the word search problem, consider moving the sofar set inside the dfs function to avoid potential issues with multiple calls. Alternatively, use the board itself to mark visited cells, which is more memory-efficient.
• The N-Queens solution is well done. The use of helper functions (okay_to_place, form_a_board) improves readability. However, the form_a_board function is not used in the final solution, which could be confusing. It's good practice to remove unused code.
• Both solutions could benefit from more comments explaining the logic, especially the backtracking steps.
