--- Day 3: Lobby ---
-
-You descend a short staircase, enter the surprisingly vast lobby, and are quickly cleared by the security checkpoint. When you get to the main elevators, however, you discover that each one has a red light above it: they're all offline.
-
-"Sorry about that," an Elf apologizes as she tinkers with a nearby control panel. "Some kind of electrical surge seems to have fried them. I'll try to get them online soon."
-
-You explain your need to get further underground. "Well, you could at least take the escalator down to the printing department, not that you'd get much further than that without the elevators working. That is, you could if the escalator weren't also offline."
-
-"But, don't worry! It's not fried; it just needs power. Maybe you can get it running while I keep working on the elevators."
-
-There are batteries nearby that can supply emergency power to the escalator for just such an occasion. The batteries are each labeled with their joltage rating, a value from 1 to 9. You make a note of their joltage ratings (your puzzle input). For example:
-
-987654321111111
-811111111111119
-234234234234278
-818181911112111
-
-The batteries are arranged into banks; each line of digits in your input corresponds to a single bank of batteries. Within each bank, you need to turn on exactly two batteries; the joltage that the bank produces is equal to the number formed by the digits on the batteries you've turned on. For example, if you have a bank like 12345 and you turn on batteries 2 and 4, the bank would produce 24 jolts. (You cannot rearrange batteries.)
-
-You'll need to find the largest possible joltage each bank can produce. In the above example:
-
-    In 987654321111111, you can make the largest joltage possible, 98, by turning on the first two batteries.
-    In 811111111111119, you can make the largest joltage possible by turning on the batteries labeled 8 and 9, producing 89 jolts.
-    In 234234234234278, you can make 78 by turning on the last two batteries (marked 7 and 8).
-    In 818181911112111, the largest joltage you can produce is 92.
-
-The total output joltage is the sum of the maximum joltage from each bank, so in this example, the total output joltage is 98 + 89 + 78 + 92 = 357.
-
-There are many batteries in front of you. Find the maximum joltage possible from each bank; what is the total output joltage?

--- Part Two ---
-
-The escalator doesn't move. The Elf explains that it probably needs more joltage to overcome the static friction of the system and hits the big red "joltage limit safety override" button. You lose count of the number of times she needs to confirm "yes, I'm sure" and decorate the lobby a bit while you wait.
-
-Now, you need to make the largest joltage by turning on exactly twelve batteries within each bank.
-
-The joltage output for the bank is still the number formed by the digits of the batteries you've turned on; the only difference is that now there will be 12 digits in each bank's joltage output instead of two.
-
-Consider again the example from before:
-
-987654321111111
-811111111111119
-234234234234278
-818181911112111
-
-Now, the joltages are much larger:
-
-    In 987654321111111, the largest joltage can be found by turning on everything except some 1s at the end to produce 987654321111.
-    In the digit sequence 811111111111119, the largest joltage can be found by turning on everything except some 1s, producing 811111111119.
-    In 234234234234278, the largest joltage can be found by turning on everything except a 2 battery, a 3 battery, and another 2 battery near the start to produce 434234234278.
-    In 818181911112111, the joltage 888911112111 is produced by turning on everything except some 1s near the front.
-
-The total output joltage is now much larger: 987654321111 + 811111111119 + 434234234278 + 888911112111 = 3121910778619.
-
-What is the new total output joltage?

+--- Day 4: Printing Department ---
+
+You ride the escalator down to the printing department. They're clearly getting ready for Christmas; they have lots of large rolls of paper everywhere, and there's even a massive printer in the corner (to handle the really big print jobs).
+
+Decorating here will be easy: they can make their own decorations. What you really need is a way to get further into the North Pole base while the elevators are offline.
+
+"Actually, maybe we can help with that," one of the Elves replies when you ask for help. "We're pretty sure there's a cafeteria on the other side of the back wall. If we could break through the wall, you'd be able to keep moving. It's too bad all of our forklifts are so busy moving those big rolls of paper around."
+
+If you can optimize the work the forklifts are doing, maybe they would have time to spare to break through the wall.
+
+The rolls of paper (@) are arranged on a large grid; the Elves even have a helpful diagram (your puzzle input) indicating where everything is located.
+
+For example:

+
+The forklifts can only access a roll of paper if there are fewer than four rolls of paper in the eight adjacent positions. If you can figure out which rolls of paper the forklifts can access, they'll spend less time looking and more time breaking down the wall to the cafeteria.
+
+In this example, there are 13 rolls of paper that can be accessed by a forklift (marked with x):

+
+Now, the Elves just need help accessing as much of the paper as they can.
+
+Once a roll of paper can be accessed by a forklift, it can be removed. Once a roll of paper is removed, the forklifts might be able to access more rolls of paper, which they might also be able to remove. How many total rolls of paper could the Elves remove if they keep repeating this process?
+
+Starting with the same example as above, here is one way you could remove as many rolls of paper as possible, using highlighted @ to indicate that a roll of paper is about to be removed, and using x to indicate that a roll of paper was just removed:

+--- Day 5: Cafeteria ---
+
+As the forklifts break through the wall, the Elves are delighted to discover that there was a cafeteria on the other side after all.
+
+You can hear a commotion coming from the kitchen. "At this rate, we won't have any time left to put the wreaths up in the dining hall!" Resolute in your quest, you investigate.
+
+"If only we hadn't switched to the new inventory management system right before Christmas!" another Elf exclaims. You ask what's going on.
+
+The Elves in the kitchen explain the situation: because of their complicated new inventory management system, they can't figure out which of their ingredients are fresh and which are spoiled. When you ask how it works, they give you a copy of their database (your puzzle input).
+
+The database operates on ingredient IDs. It consists of a list of fresh ingredient ID ranges, a blank line, and a list of available ingredient IDs. For example:
+
+3-5
+10-14
+16-20
+12-18
+
+1
+5
+8
+11
+17
+32
+
+The fresh ID ranges are inclusive: the range 3-5 means that ingredient IDs 3, 4, and 5 are all fresh. The ranges can also overlap; an ingredient ID is fresh if it is in any range.
+
+The Elves are trying to determine which of the available ingredient IDs are fresh. In this example, this is done as follows:
+
+    Ingredient ID 1 is spoiled because it does not fall into any range.
+    Ingredient ID 5 is fresh because it falls into range 3-5.
+    Ingredient ID 8 is spoiled.
+    Ingredient ID 11 is fresh because it falls into range 10-14.
+    Ingredient ID 17 is fresh because it falls into range 16-20 as well as range 12-18.
+    Ingredient ID 32 is spoiled.
+
+So, in this example, 3 of the available ingredient IDs are fresh.
+
+Process the database file from the new inventory management system. How many of the available ingredient IDs are fresh?

+--- Part Two ---
+
+The Elves start bringing their spoiled inventory to the trash chute at the back of the kitchen.
+
+So that they can stop bugging you when they get new inventory, the Elves would like to know all of the IDs that the fresh ingredient ID ranges consider to be fresh. An ingredient ID is still considered fresh if it is in any range.
+
+Now, the second section of the database (the available ingredient IDs) is irrelevant. Here are the fresh ingredient ID ranges from the above example:
+
+3-5
+10-14
+16-20
+12-18
+
+The ingredient IDs that these ranges consider to be fresh are 3, 4, 5, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, and 20. So, in this example, the fresh ingredient ID ranges consider a total of 14 ingredient IDs to be fresh.
+
+Process the database file again. How many ingredient IDs are considered to be fresh according to the fresh ingredient ID ranges?
