You are given an integer array nums. You need to create a 2D array from nums satisfying the following conditions:
nums.Return the resulting array. If there are multiple answers, return any of them.
\n\nNote that the 2D array can have a different number of elements on each row.
\n\n\n
Example 1:
\n\n\nInput: nums = [1,3,4,1,2,3,1]\nOutput: [[1,3,4,2],[1,3],[1]]\nExplanation: We can create a 2D array that contains the following rows:\n- 1,3,4,2\n- 1,3\n- 1\nAll elements of nums were used, and each row of the 2D array contains distinct integers, so it is a valid answer.\nIt can be shown that we cannot have less than 3 rows in a valid array.\n\n
Example 2:
\n\n\nInput: nums = [1,2,3,4]\nOutput: [[4,3,2,1]]\nExplanation: All elements of the array are distinct, so we can keep all of them in the first row of the 2D array.\n\n\n
\n
Constraints:
\n\n1 <= nums.length <= 2001 <= nums[i] <= nums.length给你一个整数数组 nums 。请你创建一个满足以下条件的二维数组：
nums 中的元素。返回结果数组。如果存在多种答案，则返回其中任何一种。
\n\n请注意，二维数组的每一行上可以存在不同数量的元素。
\n\n\n\n
示例 1：
\n\n输入：nums = [1,3,4,1,2,3,1]\n输出：[[1,3,4,2],[1,3],[1]]\n解释：根据题目要求可以创建包含以下几行元素的二维数组：\n- 1,3,4,2\n- 1,3\n- 1\nnums 中的所有元素都有用到，并且每一行都由不同的整数组成，所以这是一个符合题目要求的答案。\n可以证明无法创建少于三行且符合题目要求的二维数组。\n\n
示例 2：
\n\n输入：nums = [1,2,3,4]\n输出：[[4,3,2,1]]\n解释：nums 中的所有元素都不同，所以我们可以将其全部保存在二维数组中的第一行。\n\n\n
