2570. Merge Two 2D Arrays by Summing Values solution Easy 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. Merge the two arrays into one array that is sorted in ascending order by id, respecting the following conditions: Only ids that appear in at least one of the two arrays should be included in the resulting array.
