Functions

func ContainsString

func ContainsString(arr []string, value string) bool

ContainsString returns whether the value is in arr.

func DedupStringArr

func DedupStringArr(input []string) []string

DedupStringArr removes duplicate string in array.

func GCD

func GCD(x, y int) int

GCD returns the greatest common divisor of x and y.

func GCDSlice

func GCDSlice(s []int) int

GCDSlice returns the greatest common divisor of a slice. It returns 1 when s is empty because that any number divided by 1 is still itself.

func Shuffle

func Shuffle(n int, swap func(int, int))

Shuffle pseudo-randomizes the order of elements. n is the number of elements. swap swaps the elements with indexes i and j. copy from rand.Shuffle of go1.10.
