Jav G-queen [FREE]

The solution uses a backtracking approach to place queens on the board. The solveNQueens method initializes the board and calls the backtrack method to start the backtracking process.

The isValid method checks if a queen can be placed at a given position on the board by checking the column and diagonals. jav g-queen

The backtrack method checks if the current row is the last row, and if so, adds the current board configuration to the result list. Otherwise, it tries to place a queen in each column of the current row and recursively calls itself. The solution uses a backtracking approach to place

The space complexity of the solution is O(N^2), where N is the number of queens. This is because we need to store the board configuration and the result list. The backtrack method checks if the current row
