Upon reaching a gondola lift station to ascend to the water source, you discover the gondola is malfunctioning. An engineer Elf needs help identifying a missing engine part, and later, the correct gear to replace.
Title: Engine Schematic Analysis
The engine schematic contains numbers and symbols, where any number adjacent to a symbol (excluding periods) is a "part number."
Task: Calculate the sum of all part numbers in the engine schematic.
Example Schematic:
467..114..
..._......
..35..633.
......#...
617_......
.....+.58.
..592.....
......755.
...$.\*....
.664.598..
In this example, the sum of the part numbers is 4361.
Solution:
To find the sum of all part numbers in the actual engine schematic:
cd Day3
cargo run --release part1This command will execute the Rust program for Part One, outputting the total sum of part numbers.
Title: Gear Ratio Calculation
A gear is any * symbol adjacent to exactly two part numbers. The gear ratio is the product of these two numbers.
Task: Find the gear ratio of every gear and add them all up.
Example Schematic:
467..114..
...*......
..35..633.
......#...
617*......
.....+.58.
..592.....
......755.
...$.*....
.664.598..
In this example, the sum of the gear ratios is 467835.
Solution:
To calculate the sum of all gear ratios in the engine schematic:
cd Day3
cargo run --release part2Running this command for Part Two will output the total sum of the gear ratios.
The puzzles for Day 3 are based on a specific engine schematic. Access the input file for these challenges here: Day 3 Input.
Completing Day 3's puzzles brought challenges in pattern recognition and algorithmic thinking, furthering my exploration in Rust programming.
