You are given two 2D integer arrays nums1 and nums2.
nums1[i] = [idi, vali] indicate that the number with the id idi has a value equal to vali.nums2[i] = [idi, vali] indicate that the number with the id idi has a value equal to vali.Each array contains unique ids and is sorted in ascending order by id.
\n\nMerge the two arrays into one array that is sorted in ascending order by id, respecting the following conditions:
\n\n0.Return the resulting array. The returned array must be sorted in ascending order by id.
\n\n\n
Example 1:
\n\n\nInput: nums1 = [[1,2],[2,3],[4,5]], nums2 = [[1,4],[3,2],[4,1]]\nOutput: [[1,6],[2,3],[3,2],[4,6]]\nExplanation: The resulting array contains the following:\n- id = 1, the value of this id is 2 + 4 = 6.\n- id = 2, the value of this id is 3.\n- id = 3, the value of this id is 2.\n- id = 4, the value of this id is 5 + 1 = 6.\n\n\n
Example 2:
\n\n\nInput: nums1 = [[2,4],[3,6],[5,5]], nums2 = [[1,3],[4,3]]\nOutput: [[1,3],[2,4],[3,6],[4,3],[5,5]]\nExplanation: There are no common ids, so we just include each id with its value in the resulting list.\n\n\n
\n
Constraints:
\n\n1 <= nums1.length, nums2.length <= 200nums1[i].length == nums2[j].length == 21 <= idi, vali <= 1000给你两个 二维 整数数组 nums1 和 nums2.
nums1[i] = [idi, vali] 表示编号为 idi 的数字对应的值等于 vali 。nums2[i] = [idi, vali] 表示编号为 idi 的数字对应的值等于 vali 。每个数组都包含 互不相同 的 id ，并按 id 以 递增 顺序排列。
\n\n请你将两个数组合并为一个按 id 以递增顺序排列的数组，并符合下述条件：
\n\n0 。返回结果数组。返回的数组需要按 id 以递增顺序排列。
\n\n\n\n
示例 1：
\n\n输入：nums1 = [[1,2],[2,3],[4,5]], nums2 = [[1,4],[3,2],[4,1]]\n输出：[[1,6],[2,3],[3,2],[4,6]]\n解释：结果数组中包含以下元素：\n- id = 1 ，对应的值等于 2 + 4 = 6 。\n- id = 2 ，对应的值等于 3 。\n- id = 3 ，对应的值等于 2 。\n- id = 4 ，对应的值等于5 + 1 = 6 。\n\n\n
示例 2：
\n\n输入：nums1 = [[2,4],[3,6],[5,5]], nums2 = [[1,3],[4,3]]\n输出：[[1,3],[2,4],[3,6],[4,3],[5,5]]\n解释：不存在共同 id ，在结果数组中只需要包含每个 id 和其对应的值。\n\n\n
