Notes on how to use AWS SNS:

1.  Subscribe an HTTP endpoint (i.e. http://myhost/sns_endpoint) on AWS Console
2.  AWS will send subscription confirmation right away
3.  SNS_controller responds to subscription confirmation by sending confirmation using Fog.  
4.  Once AWS is happy, you can start sending notifications to your end point via SNS.

;;;A palindromic number reads the same both ways.
;;;The largest palindrome made from the product of two 2-digit numbers is 9009 = 91 99.
;;;Find the largest palindrome made from the product of two 3-digit numbers.

;;;左右どちらから読んでも同じ値になる数を回文数という。 2桁の数の積で表される回文数のうち、
;;;最大のものは 9009 = 91 × 99 である。
;;;では、3桁の数の積で表される回文数のうち最大のものはいくらになるか。
