Title: Google puzzle Post by Ulkesh on Sep 16th, 2004, 11:46am http://www.npr.org/features/feature.php?wfId=3916173 All the info you need for this puzzle is in this link. Apparently Google is looking for engineers and has set a series of puzzles for job-hunters to attempt. The 1st puzzle is to go to the website http://www.{first 10-digit prime found in consecutive digits of e}.com Good luck! |

Title: Re: Google puzzle Post by towr on Sep 16th, 2004, 12:46pm that was rather easy.. Of course the first answer can be easily found through google ::) And the second using the integer sequence database you all should know how to find.. And that's it allready, apparantly.. |

Title: Re: Google puzzle Post by Grimbal on Sep 16th, 2004, 2:43pm That sequence is in a integer sequence database? We probably don't have the same solutions. ??? |

Title: Re: Google puzzle Post by Sir Col on Sep 16th, 2004, 4:34pm That second puzzle is a real stinker! It was only when I was checking divisibility that I stumbled on the first necessary insight. It was pure luck that I guessed the connection with the first puzzle. You can use a string containing the digits of e to solve both puzzles; I found this one containing a little over five million digits! ::) http://antwrp.gsfc.nasa.gov/htmltest/gifcity/e.5mil |

Title: Re: Google puzzle Post by Grimbal on Sep 17th, 2004, 6:26am Someone asked whether it is the HR or PR of Google who published the puzzle. The puzzle is so easy (it doesn't even require a fast primality test) that it must be the PR. It is just a way to tell people that Google is a smart company that hires smart people. I don't think it makes a difference, when you send your resume, whether you solved it or not. |

Title: Re: Google puzzle Post by Barukh on Oct 31st, 2004, 11:46pm A friend of mine sent me the following link (quite new): Google Working to Recruit Brainy Elite (http://biz.yahoo.com/ap/041026/googling_engineers_1.html) It mentions some questions already discussed in this thread. What was more interesting for me, is the paragraph on 21-question aptitude test. It includes the question about 2-dimensional lattice of resistors, posted here by THUD&BLUNDER in the easy ;D section. I just wonder: how many of 2,700 google workers are capable of solving this by themselves? |

Title: Re: Google puzzle Post by Sir Col on Nov 1st, 2004, 10:03am MathWorld published a detailed analysis of the original questions and some of the aptitude test questions: http://mathworld.wolfram.com/news/2004-10-13/google/ The answer to the resistor problem is published (#10). I almost kicked myself when I saw how easy it was and now I wonder why I couldn't answer it when T&B posted it here! ::) |

Very interesting! Thanks for posting the link. Quote:
I noticed that MathWorld put their analysis online at Oct 13. THUD&BLUNDER put the following 2 problems two days later: Resistors (http://www.ocf.berkeley.edu/~wwu/cgi-bin/yabb/YaBB.cgi?board=riddles_easy;action=display;num=1097845426) Next Number? (http://www.ocf.berkeley.edu/~wwu/cgi-bin/yabb/YaBB.cgi?board=riddles_easy;action=display;num=1097846121) THUD&BLUNDER, are you working for Mr. Wolfram? ;D And now I am really afraid he will execute me... :'( |

Title: Re: Google puzzle Post by THUDandBLUNDER on Nov 2nd, 2004, 2:33am Sorry about that, guys. I didn't read the question properly and didn't know the answer when I posted. on 11/01/04 at 23:42:09, Barukh wrote:
You can relax, but there may well be a contract out on Sir Col. :D on 11/01/04 at 10:03:07, Sir Col wrote:
