+
+--- Day 7: Camel Cards ---
+
+   Your all-expenses-paid trip turns out to be a one-way, five-minute ride in
+   an [16]airship. (At least it's a cool airship!) It drops you off at the
+   edge of a vast desert and descends back to Island Island.
+
+   "Did you bring the parts?"
+
+   You turn around to see an Elf completely covered in white clothing,
+   wearing goggles, and riding a large [17]camel.
+
+   "Did you bring the parts?" she asks again, louder this time. You aren't
+   sure what parts she's looking for; you're here to figure out why the sand
+   stopped.
+
+   "The parts! For the sand, yes! Come with me; I will show you." She beckons
+   you onto the camel.
+
+   After riding a bit across the sands of Desert Island, you can see what
+   look like very large rocks covering half of the horizon. The Elf explains
+   that the rocks are all along the part of Desert Island that is directly
+   above Island Island, making it hard to even get there. Normally, they use
+   big machines to move the rocks and filter the sand, but the machines have
+   broken down because Desert Island recently stopped receiving the parts
+   they need to fix the machines.
+
+   You've already assumed it'll be your job to figure out why the parts
+   stopped when she asks if you can help. You agree automatically.
+
+   Because the journey will take a few days, she offers to teach you the game
+   of Camel Cards. Camel Cards is sort of similar to [18]poker except it's
+   designed to be easier to play while riding a camel.
+
+   In Camel Cards, you get a list of hands, and your goal is to order them
+   based on the strength of each hand. A hand consists of five cards labeled
+   one of A, K, Q, J, T, 9, 8, 7, 6, 5, 4, 3, or 2. The relative strength of
+   each card follows this order, where A is the highest and 2 is the lowest.
+
+   Every hand is exactly one type. From strongest to weakest, they are:
+
+     • Five of a kind, where all five cards have the same label: AAAAA
+     • Four of a kind, where four cards have the same label and one card has
+       a different label: AA8AA
+     • Full house, where three cards have the same label, and the remaining
+       two cards share a different label: 23332
+     • Three of a kind, where three cards have the same label, and the
+       remaining two cards are each different from any other card in the
+       hand: TTT98
+     • Two pair, where two cards share one label, two other cards share a
+       second label, and the remaining card has a third label: 23432
+     • One pair, where two cards share one label, and the other three cards
+       have a different label from the pair and each other: A23A4
+     • High card, where all cards' labels are distinct: 23456
+
+   Hands are primarily ordered based on type; for example, every full house
+   is stronger than any three of a kind.
+
+   If two hands have the same type, a second ordering rule takes effect.
+   Start by comparing the first card in each hand. If these cards are
+   different, the hand with the stronger first card is considered stronger.
+   If the first card in each hand have the same label, however, then move on
+   to considering the second card in each hand. If they differ, the hand with
+   the higher second card wins; otherwise, continue with the third card in
+   each hand, then the fourth, then the fifth.
+
+   So, 33332 and 2AAAA are both four of a kind hands, but 33332 is stronger
+   because its first card is stronger. Similarly, 77888 and 77788 are both a
+   full house, but 77888 is stronger because its third card is stronger (and
+   both hands have the same first and second card).
+
+   To play Camel Cards, you are given a list of hands and their corresponding
+   bid (your puzzle input). For example:
+
+ 32T3K 765
+ T55J5 684
+ KK677 28
+ KTJJT 220
+ QQQJA 483
+
+   This example shows five hands; each hand is followed by its bid amount.
+   Each hand wins an amount equal to its bid multiplied by its rank, where
+   the weakest hand gets rank 1, the second-weakest hand gets rank 2, and so
+   on up to the strongest hand. Because there are five hands in this example,
+   the strongest hand will have rank 5 and its bid will be multiplied by 5.
+
+   So, the first step is to put the hands in order of strength:
+
+     • 32T3K is the only one pair and the other hands are all a stronger
+       type, so it gets rank 1.
+     • KK677 and KTJJT are both two pair. Their first cards both have the
+       same label, but the second card of KK677 is stronger (K vs T), so
+       KTJJT gets rank 2 and KK677 gets rank 3.
+     • T55J5 and QQQJA are both three of a kind. QQQJA has a stronger first
+       card, so it gets rank 5 and T55J5 gets rank 4.
+
+   Now, you can determine the total winnings of this set of hands by adding
+   up the result of multiplying each hand's bid with its rank (765 * 1 + 220
+   * 2 + 28 * 3 + 684 * 4 + 483 * 5). So the total winnings in this example
+   are 6440.
+
+   Find the rank of every hand in your set. What are the total winnings?
+
+   Your puzzle answer was 251287184.
+
+--- Part Two ---
+
+   To make things a little more interesting, the Elf introduces one
+   additional rule. Now, J cards are [19]jokers - wildcards that can act like
+   whatever card would make the hand the strongest type possible.
+
+   To balance this, J cards are now the weakest individual cards, weaker even
+   than 2. The other cards stay in the same order: A, K, Q, T, 9, 8, 7, 6, 5,
+   4, 3, 2, J.
+
+   J cards can pretend to be whatever card is best for the purpose of
+   determining hand type; for example, QJJQ2 is now considered four of a
+   kind. However, for the purpose of breaking ties between two hands of the
+   same type, J is always treated as J, not the card it's pretending to be:
+   JKKK2 is weaker than QQQQ2 because J is weaker than Q.
+
+   Now, the above example goes very differently:
+
+ 32T3K 765
+ T55J5 684
+ KK677 28
+ KTJJT 220
+ QQQJA 483
+
+     • 32T3K is still the only one pair; it doesn't contain any jokers, so
+       its strength doesn't increase.
+     • KK677 is now the only two pair, making it the second-weakest hand.
+     • T55J5, KTJJT, and QQQJA are now all four of a kind! T55J5 gets rank 3,
+       QQQJA gets rank 4, and KTJJT gets rank 5.
+
+   With the new joker rule, the total winnings in this example are 5905.
+
+   Using the new joker rule, find the rank of every hand in your set. What
+   are the new total winnings?
+
+   Your puzzle answer was 250757288.
+
+   Both parts of this puzzle are complete! They provide two gold stars: **
+
+   At this point, you should [20]return to your Advent calendar and try
+   another puzzle.

+   If you still want to see it, you can [21]get your puzzle input.
