**Help**

I do my best to solve these puzzle on my own, but I do have a job and other responsibilities.

So if a puzzle takes too long, I will find help from others working on Advent of Code 2021.

Below are the attributions to these other programmers.

1. I received help on part 2 of day 14 from [kresimir-lukin](https://github.com/kresimir-lukin/AdventOfCode2021/blob/main/day14.py).

2. I received help on day 20 from [fridokus](https://github.com/fridokus/advent-of-code/blob/master/2021/20.py).

## Details

### Installation

This project can be installed as a Python package using `pip`.

Once it is installed, the code for the challenges can be executed using the CLI command as demonstrated later.

```bash

# pyenv local 3.9.9

python3 -m venv .env # or `pyenv exec python3 -m venv .env`

pip install --upgrade pip

pip install git+https://github.com/jhrcook/advent-of-code_2021.git

```

### Development setup

The steps to setting up the development version of this project are shown below.

```bash

pyenv local 3.9.9

pyenv exec python3 -m venv .env

source .env/bin/activate

pip install --upgrade pip

pip install flit

flit install

```

### Run the challenges

It is possible to run the code for a single day's challenge as demonstrated:

```bash

aoc21 --day 1

#> Day 1 part 1 answer: 1226

#> Day 1 part 2 answer: 1252

```

If no day is supplied as input, then the code for all of the challenges is executed in order.

```bash

aoc21

#> Day 1 part 1 answer: 1226

#> Day 1 part 2 answer: 1252

#> Day 2 part 1 answer: 1507611

#> ...

```

Alternatively, if you have the development system setup, you can use [`tox`]https://tox.wiki).

```bash

tox

#> .package recreate: /Users/admin/Developer/Python/advent-of-code_2021/.tox/.package

#> .package installdeps: flit_core >=3.2,<4

#> ...

```

### Organization

This repository is actually a Python package with all of the code in the [advent_of_code](./advent_of_code/) directory.

Within there, all of the challenges are in the [advent_of_code/challenges](./advent_of_code/challenges) sub-module where are day has a separate file.

Each of these "day"s can be run by Python to complete the challenge.
