+# Day 2 - Sort & Merge
+
+> There are multiple elves that help Santa to keep track of all of the people on
+> his list. Every person on the list has a unique number assigned to help
+> identify him or her, but in order to work efficiently, the elves work in three
+> groups. This causes people to be listed across the separate and exclusive
+> lists.
+>
+> i.e. If Prof. Lawrence J. Hubert is assigned number 9780824776176 on list A,
+> no other person will be assigned his number and he will not be on list B or
+> list C.
+
+Santa likes to review the list in numerical order, but the elves build each list
+by randomly assigning the next person or any list.
+
+Write a function that helps Jingles merge the three numerically sorted lists
+into a new sorted list for Santa to review.
+
+Example: [1,4,9],[3,5,8],[2,6,7] → [1,2,3,4,5,6,7,8,9]
+
+Bonus: Can you sort into a new list without starting with an empty list?
