func RandStringWithCharset(length int, charset string) string

Returns a random string with length and a charset (e.g. “abcdefghijklmnopqrstuvwxyz0123456789”).

str = RandStringWithCharset(5,"abcd")

The above command will return a string of length = 5 having random characters from the set “abcd”.

func RandString(length int) string

Returns a random string with length and the charset (“abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789”).

str = RandString(5)

The above command will return a random string of length = 5.

func ShuffleIntSlice(slice []int)

string_arr:= [3]string{"git","rocks","hello"}
ShuffleStringSlice(string_arr[:])

func ShuffleByteSlice(slice []byte)

shuffles all entries of an []byte

byte_arr:= [3]byte{'g','r','h'}
ShuffleByteSlice(byte_arr[:])

func UpArrow(base uint64, exponant uint64, upArrowAmount uint64) uint64
