Leetcode(Python):排列问题(permutation) Permutation 返回nums矩阵的所有排列情况。例子:【1,2,3】首先把1加入到原始矩阵中,然后选择2放的位置,2放的位置有两个选择1前面或者后面,因此产生两个子列表{1,2}、{2,1}。对于第三个数,在前面的每个子列表中又有len(字列表)+1的位置可以选择。这样就完成了全体排...
DP 常见的三种优化方式见 LeetCode 583 这题的思路。 本题可以采用滚动数组的方式进行优化,因为每一行的状态依赖上一行的所有状态, 所以无法采用其他两种方式进行优化。 使用滚动数组的话,能将空间复杂度从 O(nC) 优化为 O(C) ,本实现为了便于理解,不做优化处理。 进阶优化:使用矩阵快速幂处理,可以将时间复杂度...
