Instructions

Write a program that determines if a given number is a power of 2. A number n is a power of 2 if it meets the following condition: n = 2 ^m where m is another integer number.

For example, 4 = 2 ² or 16 = 2 ⁴ are power of 2 numbers while 24 is not.

This program must print true if the given number is a power of 2, otherwise it has to print false.

If there is more than one or no argument, the program should print nothing.
When there is only one argument, it will always be a positive valid int.

Usage :

$ go run . 2 | cat -e
true$
$ go run . 64
true
$ go run . 513
false
$ go run .
$ go run . 64 1024
$
