Advent of Code – Rust Solutions

Personal solutions for the Advent of Code challenges, organized by year and executed through a single runner binary.

---

Usage

The binary accepts two parameters:

Flag	Meaning	Example
--year, -y	Target Advent of Code year	-y 2024
--day, -d	Target day (1–25). Accepts 1 or 01	-d 1

Internally, days are formatted as two digits, so both 1 and 01 work.

---

Running with Cargo

Arguments to your binary must come after --:

cargo run -- -y 2024 -d 1

Example

Run Day 01 – Year 2024:

cargo run -- -y 2024 -d 1

---

Running the compiled binary

Build in release mode:

cargo build --release

Execute the binary:

./target/release/advent-of-code -y 2024 -d 1

---

Input files

Puzzle inputs must follow this layout:

inputs/y{year}/{day}.txt

Where:

Component	Description	Example
{year}	Four-digit year	y2024
{day}	Day in one or two digits	01 or 1

Example:

inputs/y2024/01.txt

or

inputs/y2024/1.txt
