You are given a 0-indexed array of non-negative integers nums. For each integer in nums, you must find its respective second greater integer.
The second greater integer of nums[i] is nums[j] such that:
j > inums[j] > nums[i]k such that nums[k] > nums[i] and i < k < j.If there is no such nums[j], the second greater integer is considered to be -1.
[1, 2, 4, 3], the second greater integer of 1 is 4, 2 is 3, and that of 3 and 4 is -1.Return an integer array answer, where answer[i] is the second greater integer of nums[i].
\n
Example 1:
\n\n\nInput: nums = [2,4,0,9,6]\nOutput: [9,6,6,-1,-1]\nExplanation:\n0th index: 4 is the first integer greater than 2, and 9 is the second integer greater than 2, to the right of 2.\n1st index: 9 is the first, and 6 is the second integer greater than 4, to the right of 4.\n2nd index: 9 is the first, and 6 is the second integer greater than 0, to the right of 0.\n3rd index: There is no integer greater than 9 to its right, so the second greater integer is considered to be -1.\n4th index: There is no integer greater than 6 to its right, so the second greater integer is considered to be -1.\nThus, we return [9,6,6,-1,-1].\n\n\n
Example 2:
\n\n\nInput: nums = [3,3]\nOutput: [-1,-1]\nExplanation:\nWe return [-1,-1] since neither integer has any integer greater than it.\n\n\n
\n
Constraints:
\n\n1 <= nums.length <= 1050 <= nums[i] <= 109给你一个下标从 0 开始的非负整数数组 nums 。对于 nums 中每一个整数，你必须找到对应元素的 第二大 整数。
如果 nums[j] 满足以下条件，那么我们称它为 nums[i] 的 第二大 整数：
j > inums[j] > nums[i]k 满足 i < k < j 且 nums[k] > nums[i] 。如果不存在 nums[j] ，那么第二大整数为 -1 。
[1, 2, 4, 3] 中，1 的第二大整数是 4 ，2 的第二大整数是 3 ，3 和 4 的第二大整数是 -1 。请你返回一个整数数组 answer ，其中 answer[i]是 nums[i] 的第二大整数。
\n\n
示例 1：
\n\n\n输入：nums = [2,4,0,9,6]\n输出：[9,6,6,-1,-1]\n解释：\n下标为 0 处：2 的右边，4 是大于 2 的第一个整数，9 是第二个大于 2 的整数。\n下标为 1 处：4 的右边，9 是大于 4 的第一个整数，6 是第二个大于 4 的整数。\n下标为 2 处：0 的右边，9 是大于 0 的第一个整数，6 是第二个大于 0 的整数。\n下标为 3 处：右边不存在大于 9 的整数，所以第二大整数为 -1 。\n下标为 4 处：右边不存在大于 6 的整数，所以第二大整数为 -1 。\n所以我们返回 [9,6,6,-1,-1] 。\n\n\n
示例 2：
\n\n\n输入：nums = [3,3]\n输出：[-1,-1]\n解释：\n由于每个数右边都没有更大的数，所以我们返回 [-1,-1] 。\n\n\n
