• Write a function that merges two sorted lists into a new sorted list.
• def merge_sorted_lists(l1, l2):
      merged_list = []
      while l1 and l2:
          if l1[0] < l2[0]:
              merged_list.append(l1.pop(0))
          else:
              merged_list.append(l2.pop(0))
      merged_list.extend(l1 or l2)
      return merged_list
