| That won't work because you have two ones and a zero in the ones spot. |

Laramie: I believe it's the OUTCOME that opens the door etc. The outcome of 0001000126 is 6210001000, which we know should open the door.

groza,
My understanding is that the door opens if the input is the same as the output. |

| given 10 digit number, x, and its output, y, if setting the dials on the door to x opens the floor, then setting them to y will cause the poison to flood the room. And, conversly, if x brings poison the room, y will open the floor. |
If x is 0000001126 then y is 6210001000. Since we already know that that value of y will not set off either trap, then x won't either because it would imply y setting off the other.
After rereading the problem I don't think the computer opens the door, it sounds like the door opens itself and the computer just chooses a trap.

btw the solution clearly states that any number that EVENTUALLY generates a cycle is good enough to free the prisoner.
Also, mith might like to know: seven-ten-hundred-thousand + 6300...0100 are the only cycle of two, and there are no cycles of 3/4/5.../8/9. I haven't bothered to do more, although it would be very easy. |
