Ruby Newbie: What's wrong with my code?
Hallo,
I've been having a bash at the Google AI contest, writing my AI in Ruby, with mixed results. I'm just learning the language and I think I have a long way to go but I'm enjoying the process. Anyway, I wrote the following method because I wanted to be able to sort one list according to the values in another list. (Basically, when I start the game, I want to measure how far away every planet is from my starting planets and then sort the list of planets according to how far away they are). This is what I came up with, but in some mysterious way I haven't been able to work out, it keeps crashing. Any ideas why?
Any advice or help greatly appreciated.

def doublesorter(firstlist, secondlist)
ind = 0
while ind < firstlist.length - 2
if firstlist[ind] < firstlist[ind + 1]
ind += 1
else
firstlist.push(firstlist[ind])
secondlist.push(secondlist[ind])
firstlist.delete_at(ind)
secondlist.delete_at(ind)
ind = 0
end
end
return firstlist, secondlist
end Any advice or help greatly appreciated.
