i'm glad you like it Nuke...thought a programming chall would be good...yes you can do it with pen and paper but it's easier to write a program and do it for you in 2 seconds...anyone who knows what it's about will write a program in 15 minutes... |

I agreed, the coding a program is a better way to solve the challenge. but as i said yesterday was reaaaallyyyy lazy... or i have just time to waste

I was a good little programmer and wrote a program to do this. The shortest path I get has length 144 (I hope this number is not much of a spoiler). In fact, I got 4 paths of that length -- two of them are a reversal of the other two -- but none of them work as the answer. Is there an even shorter path that my program somehow missed? |

hi alice...i think you missed something with your program...the right length is bigger and you get 2 possible of these CIRCLES with the same length...what programming language did you used?if you want send me your code and i'll take a look at it... EDIT just changed the weight of one edge...just to make the matrix symetrical... but it has nothing to do with the solution:) |

I've redone it as a circle, but still didn't get the right answer, because the shortest path my program found is actually 7 shorter than the intended path. I will msg you with with more details. |

What should the solution look like? Is it something like "5O7LI0PNU...", or I should add hyphens/commas/god knows what? And can i assume that "7" is the start and the end? |

Yes vasis, but it's not that big what you will have to enter, and it makes sense Bregi |

Hi, as there are some errors on this chall I add a comment: At the end we come back to the starting point. And also, switch 'I' and 'O' on the matrix file.=> It has been fixed! |
