Answer 1

int* merge(int* A, int n1, int* B, int n2) {
  int *merged = malloc(sizeof(int) * (n1 + n2));
  int i=0, j=0, k=0;
  while (i<n1 && j<n2)
    if (A[i] < B[j])
      merged[k++] = A[i++]; 
    else
      merged[k++] = B[j++];
  while (i<n1)
    merged[k++] = A[i++]; 
  while (j<n2)
    merged[k++] = B[j++];
  return merged;
}
