2570. Merge Two 2D Arrays by Summing Values

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, respectin
