Merge two sorted arrays

Problem Merge One Sorted Array Into Another First array has n positive numbers, and they are sorted in the non-descending order. Second array has 2n numbers: first n are also positive and sorted in the same way but the last n are all zeroes. Merge the first array into the second and return the latter. You should get 2n positive integers sorted in the non-descending order. Example { "first": [1, 3, 5], "second": [2, 4, 6, 0, 0, 0] } Output: [1, 2, 3, 4, 5, 6]
