Functions

func Factorial

func Factorial(n int) uint64

Factorial calculates the factorial of the provided integer

func GetRandomInt

func GetRandomInt(maxPossibleValue int) int

GetRandomInt returns a random integer between 1 and maxPossibleValue. If maxPossibleValue is less than or equal to 0, then 0 is returned

func Permutation

func Permutation(n int, r int) float64
