	for i, j := 0, len(chars)-1; i < j; i, j = i+1, j-1 {
		chars[i], chars[j] = chars[j], chars[i]
	}
	return string(chars)
}

func main() {
	// Check the command line args length
	var argslen = len(os.Args)

	// If the length is 2, one command line arg exist

		input := os.Args[1]
		fmt.Printf("%v\n", reverse_string(input))
