Consider two arrays of integers, v1 and v2, with allocate memory of (n+m)*sizeof(int) and m*sizeof(int), respectively; In array v1, you have the first n positions filled with integers, sorted in ascendent order. In array v2, you have all m positions filled with integers, also sorted in ascendent order. Write/implement a function that return a vector of size (n+m)*sizeof(int) that have all the elements of v1 and v2, sorted in an ascendent order
