arrayOperations

Small library for performing union, intersect, difference and distinct operations on slices in goLang

I don't promise that these are optimized (not even close!), but they work :)

Usage

var a = []int{1, 1, 2, 3}
var b = []int{2, 4}

z, ok := Difference(a, b)
if !ok {
	fmt.Println("Cannot find difference")
}

slice, ok := z.Interface().([]int)
if !ok {
	fmt.Println("Cannot convert to slice")
}
fmt.Println(slice, reflect.TypeOf(slice)) // [1, 3] []int
