Next Permutation leetcode java 题目: Implement next permutation, which rearranges numbers into the lexicographically next greater permutation of numbers. If such arrangement is not possible, it must rearrange it as the lowest possible order (ie, sorted in ascending order). The replacement must be i...

class Solution: def nextPermutation(self, nums: List[int]) -> None: i = len(nums) - 2 while i >= 0 and nums[i] >= nums[i + 1]: i -= 1 if i >= 0: j = len(nums) - 1 while j >= 0 and nums[i] >= nums[j]: ...
public class Solution { public void nextPermutation(int[] nums) { if(nums.length <= 1){ return; } int i = nums.length - 2; // 找到第一个下降点,我们要把这个下降点的值增加一点点 // 对于511这种情况,要把前面两个1都跳过,所以要包含等于 ...

然后最后想说的是,LeetCode的Discuss区里面有人用了四种解决方案解决这个问题,最让我印象深刻的是,其中一种方案只用了一条语句,因为C++的algorithm库里面有现成的next_permutation(First, last)方法解决这个问题。
