Question

Q9-2 Use the backtracking problem-solving technique to place 5 queens on a 5×5 board so that no two queens are in the same row, column, or diagonal, by placing one queen on a column each time from left to right. If there are multiples rows available for placing a queen, you are also required to consider the rows from top to bottom order. How many nodes in the state-space tree when the first solution is found?
