ispowerof2

Instructions

Write a program that determines if a given number is a power of 2.

This program must print true if the given number is a power of 2, otherwise it prints 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
$
