Dear Problem Solver,
Thanks for taking the time to play with our little brain-teaser and for sending us your solution. While you won't find a confirmation of the answer in this email, we did want to let you know that your message was received and that we'll be taking a look at it. If you submitted a resume, we'll be spending some time with that as well. If it seems like there might be a fit with a position we have open, we'll contact you within the next few days.
And as for the answer to the puzzle, we'll post the ads and the solution on our site within a couple of months, after those who are a little slower than you have had a chance to work on it a bit longer. Thanks again for your interest in Google.
