+## \-\-- Day 22: Monkey Market \-\--
+
+As you\'re all teleported deep into the jungle, a [monkey](/2022/day/11)
+steals The Historians\' device! You\'ll need get it back while The
+Historians are looking for the Chief.
+
+The monkey that stole the device seems willing to trade it, but only in
+exchange for an absurd number of bananas. Your only option is to buy
+bananas on the Monkey Exchange Market.
+
+You aren\'t sure how the Monkey Exchange Market works, but one of The
+Historians senses trouble and comes over to help. Apparently, they\'ve
+been studying these monkeys for a while and have deciphered their
+secrets.
+
+Today, the Market is full of monkeys buying *good hiding spots*.
+Fortunately, because of the time you recently spent in this jungle, you
+know lots of good hiding spots you can sell! If you sell enough hiding
+spots, you should be able to get enough bananas to buy the device back.
+
+On the Market, the buyers seem to use random prices, but their prices
+are actually only
+[pseudorandom](https://en.wikipedia.org/wiki/Pseudorandom_number_generator)!
+If you know the secret of how they pick their prices, you can wait for
+the perfect time to sell.
+
+The part about secrets is literal, the Historian explains. Each buyer
+produces a pseudorandom sequence of secret numbers where each secret is
+derived from the previous.
+
+In particular, each buyer\'s *secret* number evolves into the next
+secret number in the sequence via the following process:
+
+-   Calculate the result of *multiplying the secret number by `64`*.
+    Then, *mix* this result into the secret number. Finally, *prune* the
+    secret number.
+-   Calculate the result of *dividing the secret number by `32`*. Round
+    the result down to the nearest integer. Then, *mix* this result into
+    the secret number. Finally, *prune* the secret number.
+-   Calculate the result of *multiplying the secret number by `2048`*.
+    Then, *mix* this result into the secret number. Finally, *prune* the
+    secret number.
+
+Each step of the above process involves *mixing* and *pruning*:
+
+-   To *mix* a value into the secret number, calculate the [bitwise
+    XOR](https://en.wikipedia.org/wiki/Bitwise_operation#XOR)
+    of the given value and the secret number. Then, the secret number
+    becomes the result of that operation. (If the secret number is `42`
+    and you were to *mix* `15` into the secret number, the secret number
+    would become `37`.)
+-   To *prune* the secret number, calculate the value of the secret
+    number
+    [modulo](https://en.wikipedia.org/wiki/Modulo)
+    `16777216`. Then, the secret number becomes the result of that
+    operation. (If the secret number is `100000000` and you were to
+    *prune* the secret number, the secret number would become
+    `16113920`.)
+
+After this process completes, the buyer is left with the next secret
+number in the sequence. The buyer can repeat this process as many times
+as necessary to produce more secret numbers.
+
+So, if a buyer had a secret number of `123`, that buyer\'s next ten
+secret numbers would be:
+
+    15887950
+    16495136
+    527345
+    704524
+    1553684
+    12683156
+    11100544
+    12249484
+    7753432
+    5908254
+
+Each buyer uses their own secret number when choosing their price, so
+it\'s important to be able to predict the sequence of secret numbers for
+each buyer. Fortunately, the Historian\'s research has uncovered the
+*initial secret number of each buyer* (your puzzle input). For example:
+
+    1
+    10
+    100
+    2024
+
+This list describes the *initial secret number* of four different
+secret-hiding-spot-buyers on the Monkey Exchange Market. If you can
+simulate secret numbers from each buyer, you\'ll be able to predict all
+of their future prices.
+
+In a single day, buyers each have time to generate `2000` *new* secret
+numbers. In this example, for each buyer, their initial secret number
+and the 2000th new secret number they would generate are:
+
+    1: 8685429
+    10: 4700978
+    100: 15273692
+    2024: 8667524
+
+Adding up the 2000th new secret number for each buyer produces
+`37327623`.
+
+For each buyer, simulate the creation of 2000 new secret numbers. *What
+is the sum of the 2000th secret number generated by each buyer?*
+
+Your puzzle answer was `14476723788`.
+
+The first half of this puzzle is complete! It provides one gold star: \*
+
+## \-\-- Part Two \-\-- {#part2}
+
+Of course, the secret numbers aren\'t the prices each buyer is offering!
+That would be
+ridiculous. Instead,
+the *prices* the buyer offers are just the *ones digit* of each of their
+secret numbers.
+
+So, if a buyer starts with a secret number of `123`, that buyer\'s first
+ten *prices* would be:
+
+    3 (from 123)
+    0 (from 15887950)
+    6 (from 16495136)
+    5 (etc.)
+    4
+    4
+    6
+    4
+    4
+    2
+
+This price is the number of *bananas* that buyer is offering in exchange
+for your information about a new hiding spot. However, you still don\'t
+speak [monkey](/2022/day/21), so you can\'t negotiate with the buyers
+directly. The Historian speaks a little, but not enough to negotiate;
+instead, he can ask another monkey to negotiate on your behalf.
+
+Unfortunately, the monkey only knows how to decide when to sell by
+looking at the *changes* in price. Specifically, the monkey will only
+look for a specific sequence of *four consecutive changes* in price,
+then immediately sell when it sees that sequence.
+
+So, if a buyer starts with a secret number of `123`, that buyer\'s first
+ten secret numbers, prices, and the associated changes would be:
+
+         123: 3 
+    15887950: 0 (-3)
+    16495136: 6 (6)
+      527345: 5 (-1)
+      704524: 4 (-1)
+     1553684: 4 (0)
+    12683156: 6 (2)
+    11100544: 4 (-2)
+    12249484: 4 (0)
+     7753432: 2 (-2)
+
+Note that the first price has no associated change because there was no
+previous price to compare it with.
+
+In this short example, within just these first few prices, the highest
+price will be `6`, so it would be nice to give the monkey instructions
+that would make it sell at that time. The first `6` occurs after only
+two changes, so there\'s no way to instruct the monkey to sell then, but
+the second `6` occurs after the changes `-1,-1,0,2`. So, if you gave the
+monkey that sequence of changes, it would wait until the first time it
+sees that sequence and then immediately sell your hiding spot
+information at the current price, winning you `6` bananas.
+
+Each buyer only wants to buy one hiding spot, so after the hiding spot
+is sold, the monkey will move on to the next buyer. If the monkey
+*never* hears that sequence of price changes from a buyer, the monkey
+will never sell, and will instead just move on to the next buyer.
+
+Worse, you can only give the monkey *a single sequence* of four price
+changes to look for. You can\'t change the sequence between buyers.
+
+You\'re going to need as many bananas as possible, so you\'ll need to
+*determine which sequence* of four price changes will cause the monkey
+to get you the *most bananas overall*. Each buyer is going to generate
+`2000` secret numbers after their initial secret number, so, for each
+buyer, you\'ll have *`2000` price changes* in which your sequence can
+occur.
+
+Suppose the initial secret number of each buyer is:
+
+    1
+    2
+    3
+    2024
+
+There are many sequences of four price changes you could tell the
+monkey, but for these four buyers, the sequence that will get you the
+most bananas is `-2,1,-1,3`. Using that sequence, the monkey will make
+the following sales:
+
+-   For the buyer with an initial secret number of `1`, changes
+    `-2,1,-1,3` first occur when the price is `7`.
+-   For the buyer with initial secret `2`, changes `-2,1,-1,3` first
+    occur when the price is `7`.
+-   For the buyer with initial secret `3`, the change sequence
+    `-2,1,-1,3` *does not occur* in the first 2000 changes.
+-   For the buyer starting with `2024`, changes `-2,1,-1,3` first occur
+    when the price is `9`.
+
+So, by asking the monkey to sell the first time each buyer\'s prices go
+down `2`, then up `1`, then down `1`, then up `3`, you would get `23`
+(`7 + 7 + 9`) bananas!
+
+Figure out the best sequence to tell the monkey so that by looking for
+that same sequence of changes in every buyer\'s future prices, you get
+the most bananas in total. *What is the most bananas you can get?*
+
+Answer:
+
+Although it hasn\'t changed, you can still [get your puzzle
+input](22/input).
