Merge Two 2D Arrays by Summing Values
You are given two 2D integer arrays nums1 and nums2.
You are given two 2D integer arrays nums1 and nums2.
Each array contains unique ids and is sorted in ascending order by id.
Merge the two arrays into one array that is sorted in ascending order by id, respecting the following conditions:
Return the resulting array. The returned array must be sorted in ascending order by id.
Example 1
Input: nums1 = [[1,2],[2,3],[4,5]], nums2 = [[1,4],[3,2],[4,1]]
Output: [[1,6],[2,3],[3,2],[4,6]]
Explanation: The resulting array contains the following: - id = 1, the value of this id is 2 + 4 = 6. - id = 2, the value of this id is 3. - id = 3, the value of this id is 2. - id = 4, the value of this id is 5 + 1 = 6.
Example 2
Input: nums1 = [[2,4],[3,6],[5,5]], nums2 = [[1,3],[4,3]]
Output: [[1,3],[2,4],[3,6],[4,3],[5,5]]
Explanation: There are no common ids, so we just include each id with its value in the resulting list.
Constraints
- 1 <= nums1.length, nums2.length <= 200
- nums1[i].length == nums2[j].length == 2
- 1 <= idi, vali <= 1000
- Both arrays contain unique ids.
- Both arrays are in strictly ascending order by id.
