https://leetcode.com/problems/next-permutation/ 题意分析: 输入一个数组。输出这些数字组合的下一个比输入大的数组。如果输入的是最大的,那么输出最小的数组。比如,1,2,3输出1,3,2。而3,2,1输出1,2,3. 题目思路: 如果存在一个比输入的数组nums大的数组,那么必然存在nums[i] < nums[j](i < j)。
题目来源 https://leetcode.com/problems/next-permutation/ 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 ...

[Leetcode][python]Next Permutation/下一个排列 题目大意 寻找一组数排序的下一个序列 例如:1,2,3,下一个就是1,3,2 解题思路 官方思路(与下方相同):https://leetcode-cn.com/problems/next-permutation/solution/ http://fisherlei.blogspot.com/2012/12/leetcode-next-permutation.html 图中文字翻译: 从...
http://bangbingsyb.blogspot.com/2014/11/leetcode-next-permutation.html 讲的比我清楚。 ** 总结:Array, 在草稿纸上多画画例子,就会有思路了。 ** Anyway, Good luck, Richardo! My code: publicclassSolution{publicvoidnextPermutation(int[]nums){if(nums==null||nums.length<=1)return;intchange=-1...
publicvoidnextPermutation(int[]nums){if(nums.length<2){return;}for(inti=nums.length-2;i>=0;i--){if(nums[i]<nums[i+1]){inti1=i;inti2=i+1;// 利用二分查找寻找比nums[i1]大的下一个int[]res=newint[1];findLastGreater(nums[i1],nums,i2,nums.length-1,res);intj=res[0];//...
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。

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 ...
Can you solve this real interview question? Next Permutation - A permutation of an array of integers is an arrangement of its members into a sequence or linear order. * For example, for arr = [1,2,3], the following are all the permutations of arr: [1,2
