Functions

func AOC_2020_01 

func AOC_2020_01(cli *cli.CLI)

AOC_2020_01 is the entrypoint to the various attempts for day one

func AOC_2020_01_part1_attempt1 

func AOC_2020_01_part1_attempt1(cli *cli.CLI, logger *goutils.Logger)

AOC_2020_01_part1_attempt1 this is part 1 of day 1, attempt 1 a brute-force attempt which as the volume is small works fine we have an inner loop giving o(n^2) which again works but is not fast

func AOC_2020_01_part1_attempt2 

func AOC_2020_01_part1_attempt2(cli *cli.CLI, logger *goutils.Logger)

AOC_2020_01_part1_attempt2 in this atempt I preload an "inty" map affording go's own probably binsearch by keying on the int value itself this uses more memory (the inty map in addition to the list) but avoids an initial sort and binsearch I intend to do my own sort and binsearch as an attempt3

func AOC_2020_01_part2_attempt1 

func AOC_2020_01_part2_attempt1(cli *cli.CLI, logger *goutils.Logger)

AOC_2020_01_part2_attempt1 the second part of day 1, attempt1 this is a brute-force attempt that gets over the line in the spirit of make it work, make it fast, this is make it work so this is 3 inner loops, giving o(n^3) performance I believe - it works, it is not fast.
