Functions

func Abs

func Abs[T constraints.Integer | constraints.Float](x T) T

Abs returns the absolute (non negative) value of the input

func Count

func Count[T any](in []T, countFn func(T) bool) int

Count returns an int of the number if values in the input slice that return true when evaluated by countFn

func GCD

func GCD[T constraints.Signed | constraints.Unsigned](a, b T) T

greatest common divisor (GCD) via Euclidean algorithm

func InputFromWebsite

func InputFromWebsite(day string) string

InputFromWebsite reads the AOC_SESSION env variable to form the session cookie and then reads the input for the appropriate day. NB says are not zero prefixed so day one is just "1"

TODO oauth login via github etc. so I don't have to steal the session cookie from my browser

func Int

func Int(value string) int64

func LCM

func LCM[T constraints.Signed | constraints.Unsigned](integers ...T) T

find Least Common Multiple (LCM) via GCD

func Max

func Max[T constraints.Ordered](in ...T) T

Max returns the maximum value in the input slice

func Min

func Min[T constraints.Ordered](in ...T) T

Min returns the minimum value in the input slice

func Slice

func Slice[T any](data string, separator string, convert func(string) T) []T

Slice creates a generic slice from the split input data

func UInt

func UInt(value string) uint64
