Functions

func Difference

func Difference(a, b []int) []int

Difference returns the elements in `a` that aren't in `b`.

func Distinct

func Distinct(ints []int) []int

Distinct returns a unique slice

func DistinctFloats

func DistinctFloats(floats []float64) []float64

func GetIndxFloat64

func GetIndxFloat64(sorted []float64, x float64) int

GetIndxFloat64 performs a Go-native binary tree search on a sorted slice of floats to determine the position x would fit. modified from: https://flaviocopes.com/golang-algorithms-binary-search/

func Intersect

func Intersect(a, b []int) (set []int)

Intersect returns the intersection of 2 slices modified from: https://github.com/juliangruber/go-intersect/blob/master/intersect.go
