Advent of Code - 2018

All implementations are written in C++, mostly adhering to C++17/C++20 guidelines.

Prerequisites

• clang (>= 5.0)
• libc++ (>= 5.0)
• CMake (>= 3.11)
• macOS or Linux (only two systems I've tested on)

Compiling

• Your standard cmake-enabled project

Running

• Invoke ./Advent to execute all the days
• To run a specific day, invoke ./Advent -f <dayXX>
• To run a specific part, invoke ./Advent -p <1,2>
• To see more detailed help, consult ./Advent --help

Metrics

• Lines: Number of lines given by wc
• Code: Lines - (# preprocessor lines) - (lines with no alphanumeric chars)
• Bytes: Number of total characters
• Chars: Number of non-whitespace characters
• Time: Time in milliseconds to execute each part independently (separate runs)
• Source: link to implementation
• Headers: C++ includes used for solution

Leaderboard Highlights:

Day	Part 1	Part 2
1	52	217
