Day 8 - Advent of Code 2021. adventofcode.com . Accessed Mar 7, 2022. Part I Description You barely reach the safety of the cave when the whale smashes into the cave mouth, collapsing it. Sensors indicate another exit to this cave at a much greater depth, so you have no choice but to press on. As your submarine slowly makes its way through the cave system, you notice that the four-digit seven-segment displays in your submarine are malfunctioning; they must have been damaged during the escape.... |

Day 7 - Advent of Code 2021. adventofcode.com . Accessed Mar 5, 2022. Part I Description A giant whale has decided that your submarine is its next meal, and it’s much faster than you are. There’s nowhere to run! Suddenly, a swarm of crabs (each in its own tiny submarine - it’s too deep for them otherwise) zooms in to rescue you! They seem to be preparing to blast a hole in the ocean floor; sensors indicate a massive underground cave system just beyond where they’re aiming!... |

Day 6 - Advent of Code 2021. adventofcode.com . Accessed Mar 2, 2022. Part I Description The sea floor is getting steeper. Maybe the sleigh keys got carried this way? A massive school of glowing lanternfish swims past. They must spawn quickly to reach such large numbers - maybe exponentially quickly? You should model their growth to be sure. Although you know nothing about this specific species of lanternfish, you make some guesses about their attributes.... |

Day 4 - Advent of Code 2021. adventofcode.com . Accessed Feb 25, 2022. Part One You’re already almost 1.5km (almost a mile) below the surface of the ocean, already so deep that you can’t see any sunlight. What you can see, however, is a giant squid that has attached itself to the outside of your submarine. Maybe it wants to play bingo ?... |

Day 3 - Advent of Code 2021. adventofcode.com . Accessed Feb 23, 2022. Problem Description Part One The submarine has been making some odd creaking noises, so you ask it to produce a diagnostic report just in case. The diagnostic report (your puzzle input) consists of a list of binary numbers which, when decoded properly, can tell you many useful things about the conditions of the submarine.... |

Day 2 - Advent of Code 2021. adventofcode.com . Accessed Feb 19, 2022. Problem Statement Part One Now, you need to figure out how to pilot this thing. It seems like the submarine can take a series of commands like forward 1, down 2, or up 3: forward X increases the horizontal position by X units. down X increases the depth by X units. up X decreases the depth by X units.... |

Day 1 - Advent of Code 2021: Sonar Sweep. adventofcode.com . Accessed Feb 18, 2022. Part One As the submarine drops below the surface of the ocean, it automatically performs a sonar sweep of the nearby sea floor. On a small screen, the sonar weep report (your puzzle input) appears: each line is a measurement of the sea floor depth as the sweep looks further and further away from the submarine.... |
