In solve () you should do as last thing: return place_queen (board, 0, 0). By this you return a generator. (You could also do for solution in place_queen (board, 0, 0): yield solution but that would just relay the yielded values.)
WebMar 25, 2024 · Solving the N-Queens problem requires logical reasoning and creative problem-solving skills, making it a fascinating subject for researchers and enthusiasts alike. WebWe will first create a character array of size N*N and initialize it with ‘-‘. First, we will place a queen in a position. If after placing another queen, the previous queen is under attack, then we will try all possible positions for the queen. And if that does not work, we will backtrack to the previous queen and change its position.
