solve_n_queen函数使用回溯算法来尝试所有可能的解决方案,并打印出所有合法的解决方案。 N-Queen问题的解决方案可以应用于许多领域,例如棋类游戏、排课问题等。在云计算领域,可以将N-Queen问题看作是一种计算密集型任务,可以使用云计算平台提供的弹性计算资源来加速求解过程。 腾讯云提供了丰富的云计算产品,其中包括计...
我试图使用递归来解决 N-Queen 问题。该算法适用于 board_shape 最大5 的值。当我输入大于 5 的值时,它只会达到 5 的深度,并且不会执行任何其他操作。 如果可能,请突出显示导致问题的代码,并放置更正的代码。python algorithm recursion n-queens 1个回答 0投票 您的代码不会探索棋盘上所有可能的位置。
看到用位计算的,以后学习参考,效率两道题目都是最高的。https://github.com/zhsj/nqueen/blob/master/N%E7%9A%87%E5%90%8E%E9%97%AE%E9%A2%98.md

当您确定某个赋值arr[row][col]不安全时，永远不要为将来的测试重置它。
Both are calculated as the function of input size(n). The time complexity of an algorithm is expressed in big O notation. The efficiency of an algorithm depends on these two parameters. Types Of Time Complexity : a. Best Time Complexity: The input for which algorithm takes less time or mi...
