    asciiChars := make([]ascii, len)

    // Generate 20 random printable ascii chars that locate in [28,125)
    charstring.RandomPrintableASCII(28, 125, len)


    // Check if a string is empty
    str1, str2, str3, str4 :="", "    ", "NOT_EMPTY", "NOT EMPTY"
    // str1 is empty
    charstring.IsEmptyString(str1)

    numbers.RandomPostiveInts(0, 100, 20)
}
