 * 88. Merge Sorted Array
 *
 * Given two sorted integer arrays nums1 and nums2, merge nums2 into nums1 as one sorted array.
 *
 * Note: You may assume that nums1 has enough space (size that is greater or equal to m + n) to hold
 * additional elements from nums2. The number of elements initialized in nums1 and nums2 are m and n
 * respectively.
