Function Distinct

arrayOperations.go:90–109

Distinct returns the unique vals of a slice fmt.Println(Distinct[int]([]int{1, 1, 2, 3})) // output: [1, 2, 3]

(arrs ...[]T)

// 	fmt.Println(Distinct[int]([]int{1, 1, 2, 3}))
// 	// output: [1, 2, 3]
func Distinct[T comparable](arrs ...[]T) []T {
	// put the values of our slice into a map
	// the key's of the map will be the slice's unique values
	m := make(map[T]struct{})
	for idx1 := range arrs {
		for idx2 := range arrs[idx1] {
			m[arrs[idx1][idx2]] = struct{}{}
		}
	}

	// create the output slice and populate it with the map's keys
	res := make([]T, len(m))
	i := 0
	for k := range m {
		res[i] = k
		i++
	}

	return res
}

// Intersect returns a slice of values that are present in all of the input slices
