Straight forward problem. This is supposed to be one of the questions which potential Microsoft employees are asked. U2 have a concert that starts in 17 minutes and they must all cross a bridge to get there. All four men begin on the same side of the bridge. You must help them across to the other side. It is night. There is one flashlight. A maximum of two people can cross at one time. Any party that crosses the bridge, either 1 or 2 people, must have the flashlight with them. The flashlight must be carried back and forth, it cannot be thrown, etc. Each band member walks at a different speed. A pair must walk together at the rate of the slower man's pace: * Bono: - 1 minute to cross * Edge: - 2 minutes to cross * Adam: - 5 minutes to cross * Larry: - 10 minutes to cross For example: if Bono and Larry walk across first, 10 minutes have elapsed by the time they get to the other side of the bridge. If Larry then returns with the flashlight, a total of 20 minutes have passed and you have failed the mission. There is no trick to this. It is a simple movement of resources in the appropriate order. There are two known answers to this problem. Microsoft expects you to answer this question in under 5 minutes! My friend gave me this yesterday.... Anyone? |

Yo, Iron, fuck U2 and fuck Msoft, those are the questions for kidz in primary school (not that I am sure I could do it in 5 minutes.) I'd just get 'em all on that bridge and have Bill Gates kamikaze on it. |

No, no, don't take it personal, I just thought that some malice and bitching about people we love to hate would be helpful at this time of day (I have to go to a funeral ina couple of hours, actually and the only remotely decent online radio I'm able to get is some stupid Jazz FM crap, so bad mood is my game right now). I thought like a group therapy thing or something. |

no problem.... I am sorry to hear you have to go to a funeral in a couple of hours.... I suppose this whole post seems irrelevant.... It might be even more sad that all you have to listen too is the JAZZ station.... I'd buy you a round if I could...Cheers |

option 1 Option One Bono + Larry on back = 1 Bono back with light = 1 Bono + Adam on back = 1 bobo back with light = 1 bono + edge on back = 1 total = 5 option 2 as one set are over the second half of the bridge, get the others to meet them half way when bono returns with the light Bono + larry = 10 Bono back half way to meet adam = 0.5 bono + adam half way = 2.5 Bono back half way to meet edge = 0.5 bono and edge to other side = 1 total = 14.5 |

Iron: thanx ol'boy. Well i too feel sorry for you having to work at this time of the night. I'm not sure what happened but the moment I slagged off that Jazz FM radio, it went dumb (some wicked online magick this turns out to be, eh?). Yesterday I was listening to WFMU and it was pretty OK (cuban son, some wicked country and stuff) but I had to leave my office for a couple of hours, and when i got back my colegues apologized to me for having to turn the thing off: "It was unbearable" and I was like 'Why didn't I get to hear the music you guys thought was unbearable, I would've probably loved it. So i just treated them to Up, Bustle and Out's last CD. Cool stuff |

Ok here are some clues.... 2 people cross 1 goes back 2 people cross 1 goes back 2 people cross There are no tricks of people being carried on someone else's back, etc. OK, which people cross at which time still has to be worked out. There's only 17 mins. Larry takes 10 mins, Adam 5. You can't allow them to cross separately, since that would be 15 mins, and you'll never solve the puzzle. So they cross together. Which takes 10 mins. You can't allow either of them to make the return trip with the flashlight either, can you? Since they would still have to get back across again. That would take too long. this help anyone any???? (for the record, there is NO WAY I got this in 5 min) |

Bono + Edge -> 2 mins Bono <- 1 min Adam + Larry -> 10 min Edge <- 2 min Bono + Edge -> 2 min 17 mins, Just in time! |

WE HAVE A WINNER..... GOOD JOB ROBIN.....You will...a canned ham....:) OK - Here is the answer Bono and Edge cross the bridge - 2 minutes Bono returns with the light - 1 minute Larry and Adam cross - 10 minutes Edge returns with the light - 2 minutes Bono and Edge cross the bridge - 2 minutes. Total 17 minutes!! |

is mutilation allowed ? bono could chop chop chop the rest into little bits and carry them over in a bag or eat them before he goes over the bridge and shit them out at the other end and mould them into statues of the other band members out of excrement |

Here's the Solution! * Bono: - 1 minute to cross * Edge: - 2 minutes to cross * Adam: - 5 minutes to cross * Larry: - 10 minutes to cross Bono & edge go over - 2 mins Bono comes back - 1 mins Adam & larry go over - 10mins edge comes back - 2 mins Bono and edge go over - 2 mins Total time = 17 minutes. I'm going into work in computing, perhaps M$oft have a place for me? ;) |
