It seems there has been a mix-up. The code you provided is for the "Word Search" problem, but the problem you were asked to solve is "N-Queens". Please ensure you are submitting the correct solution for the correct problem.

For the N-Queens problem, you need to generate all distinct configurations of placing n queens on an n x n chessboard such that no two queens attack each other. The solution typically involves backtracking, where you place queens row by row and check for validity in columns and diagonals.

Here are some key points for solving N-Queens:

• Use a backtracking approach to try placing a queen in each column of the current row.
• Check if the placement is valid (no other queen in the same column, or in the same diagonal).
• When you reach the last row, convert the board state to the required output format (list of strings).
• Remember to undo the placement (backtrack) after exploring a path.

You can refer to the reference solution provided for a Java implementation. You would need to adapt it to Python if that is your language of choice.
