👑 Eight Queens: The Royal Challenge of Chessboard Conquest

👑 Unleash the Power of Eight Queens! Can You Solve This Mind-Boggling Chess Challenge?

Ahoy, fellow developers! Today, we're delving into the royal game of chess with a twist – the age-old puzzle known as the Eight Queens. So, don your thinking caps and join me on this thrilling chessboard conquest.

🤴 A Royal Conundrum

The Eight Queens puzzle, first proposed by chess composer Max Bezzel in 1848, is a captivating challenge that will test your problem-solving skills and strategic prowess. Imagine an 8x8 chessboard, and your task is to place eight queens on it, without any of them threatening each other. In chess terms, that means no queen can share the same row, column, or diagonal with another. Quite a conundrum, isn't it?

🐍 Python to the Rescue

We all love Python for its readability and elegant syntax. Let's start by solving the Eight Queens puzzle using Python. Here's a simple recursive implementation to get you started:

def is_safe(board, row, col, n):
    # Check the row on the left side
    for i in range(col):
        if board[row][i] == 1:
            return False

    # Check the upper diagonal on the left side
    for i, j in zip(range(row, -1, -1), range(col, -1, -1)):
        if board[i][j] == 1:
            return False

    # Check the lower diagonal on the left side
    for i, j in zip(range(row, n, 1), range(col, -1, -1)):
        if board[i][j] == 1:
            return False

    return True

def solve_n_queens(n):
    board = [[0] * n for _ in range(n)]

    if not solve_n_queens_util(board, 0, n):
        print("Solution does not exist")
        return False

    print_solution(board)

def solve_n_queens_util(board, col, n):
    if col >= n:
        return True

    for i in range(n):
        if is_safe(board, i, col, n):
            board[i][col] = 1

            if solve_n_queens_util(board, col + 1, n):
                return True

            board[i][col] = 0

    return False

def print_solution(board):
    for row in board:
        print(" ".join(map(str, row)))

solve_n_queens(8)

This Python code showcases the magic of recursion in finding a solution to the Eight Queens puzzle. Each queen is placed on the board one by one, and backtracking is used to explore all possible solutions.
