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 <= 1000Compiled with clang 11 using the latest C++ 20 standard.
