+
+--- Day 3: Rucksack Reorganization ---
+
+   One Elf has the important job of loading all of the rucksacks with supplies for the jungle journey. Unfortunately, that
+   Elf didn't quite follow the packing instructions, and so a few items now need to be rearranged.
+
+   Each rucksack has two large compartments. All items of a given type are meant to go into exactly one of the two
+   compartments. The Elf that did the packing failed to follow this rule for exactly one item type per rucksack.
+
+   The Elves have made a list of all of the items currently in each rucksack (your puzzle input), but they need your help
+   finding the errors. Every item type is identified by a single lowercase or uppercase letter (that is, a and A refer to
+   different types of items).
+
+   The list of items for each rucksack is given as characters all on a single line. A given rucksack always has the same
+   number of items in each of its two compartments, so the first half of the characters represent items in the first
+   compartment, while the second half of the characters represent items in the second compartment.
+
+   For example, suppose you have the following list of contents from six rucksacks:
+

+     • The first rucksack contains the items vJrwpWtwJgWrhcsFMMfFFhFp, which means its first compartment contains the items
+       vJrwpWtwJgWr, while the second compartment contains the items hcsFMMfFFhFp. The only item type that appears in both
+       compartments is lowercase p.
+     • The second rucksack's compartments contain jqHRNqRjqzjGDLGL and rsFMfFZSrLrFZsSL. The only item type that appears in
+       both compartments is uppercase L.
+     • The third rucksack's compartments contain PmmdzqPrV and vPwwTWBwg; the only common item type is uppercase P.
+     • The fourth rucksack's compartments only share item type v.
+     • The fifth rucksack's compartments only share item type t.
+     • The sixth rucksack's compartments only share item type s.
+
+   To help prioritize item rearrangement, every item type can be converted to a priority:
+
+     • Lowercase item types a through z have priorities 1 through 26.
+     • Uppercase item types A through Z have priorities 27 through 52.
+
+   In the above example, the priority of the item type that appears in both compartments of each rucksack is 16 (p), 38
+   (L), 42 (P), 22 (v), 20 (t), and 19 (s); the sum of these is 157.
+
+   Find the item type that appears in both compartments of each rucksack. What is the sum of the priorities of those item
+   types?
+
+   Your puzzle answer was 7967.
+
+--- Part Two ---
+
+   As you finish identifying the misplaced items, the Elves come to you with another issue.
+
+   For safety, the Elves are divided into groups of three. Every Elf carries a badge that identifies their group. For
+   efficiency, within each group of three Elves, the badge is the only item type carried by all three Elves. That is, if a
+   group's badge is item type B, then all three Elves will have item type B somewhere in their rucksack, and at most two of
+   the Elves will be carrying any other item type.
+
+   The problem is that someone forgot to put this year's updated authenticity sticker on the badges. All of the badges need
+   to be pulled out of the rucksacks so the new authenticity stickers can be attached.
+
+   Additionally, nobody wrote down which item type corresponds to each group's badges. The only way to tell which item type
+   is the right one is by finding the one item type that is common between all three Elves in each group.
+
+   Every set of three lines in your list corresponds to a single group, but each group can have a different badge item
+   type. So, in the above example, the first group's rucksacks are the first three lines:
+
+ vJrwpWtwJgWrhcsFMMfFFhFp
+ jqHRNqRjqzjGDLGLrsFMfFZSrLrFZsSL
+ PmmdzqPrVvPwwTWBwg
+
+   And the second group's rucksacks are the next three lines:

+
+   In the first group, the only item type that appears in all three rucksacks is lowercase r; this must be their badges. In
+   the second group, their badge item type must be Z.
+
+   Priorities for these items must still be found to organize the sticker attachment efforts: here, they are 18 (r) for the
+   first group and 52 (Z) for the second group. The sum of these is 70.
+
+   Find the item type that corresponds to the badges of each three-Elf group. What is the sum of the priorities of those
+   item types?
+
+   Your puzzle answer was 2716.
