The Blog that Noone Reads

James Polanco contributed an ActionScript version of this code. Just like the Java version, aside from a small amount of boiler plate connection code and small syntactical changes, it’s the same code. Weighing in at a svelte 694 bytes and taking just 215ms to execute, this version is the clear winner.

The ActionScript (Flash) version:

package {
    import flash.display.Sprite;
    import flash.external.ExternalInterface;

    public class FlashLib extends Sprite
    {
        public function FlashLib()
        {
            // create external interace
            ExternalInterface.addCallback("countPrimes", countPrimes);
        }

        public function countPrimes(size:int):int
        {
            var i:int, c:int, prime_count:int = 2;

            for(i = 2; i < size; i++)
            {
                for(c = 2; c < i; c++)
                {
                    if(i % c == 0)
                    {
                        prime_count++;
                        break;
                    }
                }
            }

            return prime_count;
        }
    }
}
