    88 - Merge Sorted Array.

    Easy

    You are given two integer arrays nums1 and nums2, sorted in non-decreasing order , and two integers m and n, representing the number of elements in nums1 and nums2 respectively.

    Merge nums1 and nums2 into a single array sorted in non-decreasing order.

    The final sorted array should not be returned by the function, but instead be stored inside the array nums1. To accommodate this, nums1 has a length of m + n, where the first m elements denote the elements that should be merged, and the last n elements are set to 0 and should be ignored. nums2 has a length of n.

    Example 1:

    Input: nums1 = 1,2,3,0,0,0, m = 3, nums2 = 2,5,6, n = 3

    Output: 1,2,2,3,5,6

    Explanation: The arrays we are merging are 1,2,3 and 2,5,6. The result of the merge is <ins>1</ins>,<ins>2</ins>,2,<ins>3</ins>,5,6 with the underlined elements coming from nums1.

    Example 2:

    Input: nums1 = 1, m = 1, nums2 = [], n = 0

    Output: 1

    Explanation: The arrays we are merging are 1 and []. The result of the merge is 1.

    Example 3:

    Input: nums1 = 0, m = 0, nums2 = 1, n = 1

    Output: 1

    Explanation: The arrays we are merging are [] and 1. The result of the merge is 1. Note that because m = 0, there are no elements in nums1. The 0 is only there to ensure the merge result can fit in nums1.

    Constraints:

    • nums1.length == m + n

    • nums2.length == n

    • 0 &lt;= m, n &lt;= 200

    • 1 &lt;= m + n &lt;= 200

    • <code>-10<sup>9</sup><= nums1i, nums2j<= 10<sup>9</sup></code>

    Follow up: Can you come up with an algorithm that runs in O(m + n) time?
