of distinct integers, return all the possible permutations. You can return the answer in any order.Input: nums = [0,1]
Output: [[0,1],[1,0]]
Input: nums = [1,2,3]
Output: [[1,2,3],[1,3,2],[2,1,3],[2,3,1],[3,1,2],[3,2,1]]
Input: nums = [1]
Output: [[1]]

nums
are unique.//全排列
/*
有两种思路:一是原地调换位置,二是树状分布
*/
class Solution{
//数字全排列
public List
> permute(int[] nums) {
List
> res = new List
>;
List
> res, List
