You are given a positive integer array nums and an integer k.
Choose at most k elements from nums so that their sum is maximized. However, the chosen numbers must be distinct.
Return an array containing the chosen numbers in strictly descending order.
\n\n\n
Example 1:
\n\nInput: nums = [84,93,100,77,90], k = 3
\n\nOutput: [100,93,90]
\n\nExplanation:
\n\nThe maximum sum is 283, which is attained by choosing 93, 100 and 90. We rearrange them in strictly descending order as [100, 93, 90].
Example 2:
\n\nInput: nums = [84,93,100,77,93], k = 3
\n\nOutput: [100,93,84]
\n\nExplanation:
\n\nThe maximum sum is 277, which is attained by choosing 84, 93 and 100. We rearrange them in strictly descending order as [100, 93, 84]. We cannot choose 93, 100 and 93 because the chosen numbers must be distinct.
Example 3:
\n\nInput: nums = [1,1,1,2,2,2], k = 6
\n\nOutput: [2,1]
\n\nExplanation:
\n\nThe maximum sum is 3, which is attained by choosing 1 and 2. We rearrange them in strictly descending order as [2, 1].

Constraints:
\n\n1 <= nums.length <= 1001 <= nums[i] <= 1091 <= k <= nums.length给你一个 正整数 数组 nums 和一个整数 k。
从 nums 中选择最多 k 个元素，使它们的和最大化。但是，所选的数字必须 互不相同 。
返回一个包含所选数字的数组，数组中的元素按 严格递减 顺序排序。

示例 1：
\n\n输入： nums = [84,93,100,77,90], k = 3
\n\n输出： [100,93,90]
\n\n解释：
\n\n最大和为 283，可以通过选择 93、100 和 90 实现。将它们按严格递减顺序排列，得到 [100, 93, 90]。
示例 2：
\n\n输入： nums = [84,93,100,77,93], k = 3
\n\n输出： [100,93,84]
\n\n解释：
\n\n最大和为 277，可以通过选择 84、93 和 100 实现。将它们按严格递减顺序排列，得到 [100, 93, 84]。不能选择 93、100 和另一个 93，因为所选数字必须互不相同。
示例 3：
\n\n输入： nums = [1,1,1,2,2,2], k = 6
\n\n输出： [2,1]
\n\n解释：
\n\n最大和为 3，可以通过选择 1 和 2 实现。将它们按严格递减顺序排列，得到 [2, 1]。
