Solution: Merge Sorted Array

Statement

Given two sorted integer arrays, $nums1$ and $nums2$, and the number of data elements in each array, $m$ and $n$, implement a function that merges the second array into the first one. You have to modify $nums1$ in place.

Note: Assume that $nums1$ has a size equal to $m + n$, meaning it has enough space to hold additional elements from $nums2$.

Constraints:

• nums1.length
