# AoC 2022 Day 25: Snafuinator

## Part 1

Let a Snafu number be a base 5 number with the curious property that in addition to the digits 0, 1, and 2, it has the numbers - as -1 and = as -2. Sum up a list of Snafu numbers.

# AoC 2022 Day 24: Blizzinator

## Part 1

Given a map with a series of moving walls (that wrap when the hit the edges of the simulation), calculate the fastest route from the top left to the bottom right.

# AoC 2022 Day 23: Elf Scattinator

## Part 1

Implement a cellular automaton with the following rules:

• If you have no neighbors, don’t move (important, I forgot this one for a while)
• Otherwise:
• Calculate a potential move:
• If you have no neighbors to the north, move north
• If not, check likewise for south, then west, than east
• If no other agent is moving to the same space, move to your potential move
• Otherwise, don’t move
• On each frame, rotate the order the directions are checked in (NSWE, SWEN, WENS, ENSW, NSWE, …)

# AoC 2022 Day 22: Wonderator

## Part 1

Given a map and a series of instructions formatted as distance + turn (L or R), find the final position. Any time you would walk off the edge of the map, wrap to the opposite edge.

# AoC 2022 Day 21: Yellinator

## Part 1

Given a series of equations of either the form dbpl: 5 or cczh: sllz + lgvd, determine what the value of the node labeled root is.

# AoC 2022 Day 20: Deencryptinator

## Part 1

Given a list of numbers mix them by moving each number forward/backward in the list based on it’s value. For example, in 4, -2, 5, 6, 7, 8, 9 moving the -2 will result in 4, 5, 6, 7, 8, -2, 9. Each number should be moved exactly once in the original order they appeared in the list.

# AoC 2022 Day 19: Blueprintinator

## Part 1

Given a series of given a series of blueprints, each of which gives instructions for how to build a single robot from a collection of materials that in turn will produce one of a given material per turn, determine the best order of builds to maximize your geode (the most valuable material) production for each blueprint given a time limit of 24 minutes.

# AoC 2022 Day 18: Lavinator

## Part 1

Given a list of 1x1x1 cubes, determine the total surface area of the cubes.

# AoC 2022 Day 17: Tetrisinator

## Part 1

Simulate Tetris on a 7 wide board with a given (infinitely repeated) series of left and right inputs to be applied on each frame before dropping the block and a given (infinitely repeated) set of blocks. Once 2022 blocks have been dropped, what is the total height of the placed blocks?

Given a graph of nodes, some of which have a pressure (per tick output value) and an agent that can move through the graph and activate specific nodes (so that they output their per tick value every future tick), what is the maximum total output possible in 30 steps?
