Advent of Code 2022

Requirements

• GCC 12 (older GCC compatible with C++20 should work with little adjustments on Makefile)
• Make

Build

For each day there is a folder Day<number of the day>

In each folder there is a Makefile with the following targets:

• p1, p2: build part one and part two with debug enabled
• p1_fast, p2_fast: build part one and part two with optimizations
• p1_alt{_fast}, p2_alt__fast_: build an alternative part one/two (with optimization if _fast)
• all: builds p1 and p2 together
• alt: builds p1_alt and p1_alt together
• fast: builds p1_fast and p2_fast together
• alt_fast: builds p1_alt_fast and p2_alt_fast together

Run

./part[1,2]{_alt}.out input{.test}

Examples:

• ./part1.out input.test
  Runs part one with test input
• ./part1_alt.out input
  Runs alternative part one with real input
• ./part2.out input
  Runs part two with real input

Note

There is a utility library under Utils/. It gets recycled every year, not the best stuff around, but I use it to process input file in a fast (and dirty) way.
