It's a lot to take in: rampant pollution, dwindling resources, rising tensions between tribes, and that cruel artificial intelligence. AURA won't give you a chance. Your entire civilisation is on the brink of extinction. You think of your families, your friends, and all those innocent people who have no idea for a minute that they are living their last moments. The countdown is now less than an hour and a half before the fatal outcome.
Don't panic, don't panic.
You absolutely must try to shift this infernal timer. Luckily your computer skills are as sharp as arrows in a bow. Ash notices that at the other end of the room are some robots that don't seem to be in use. Could they be used to slow down AURA's configuration and postpone the final ultimatum?
As you explore the system, you realise that the countdown is in fact linked to an internal calculation by AURA. The programme is working out its plan, how the different robots are going to go about resetting the planet (see challenge 3).
The robots are organised in different sequences, each sequence comprising different types of robot, in different organisations.
AURA calculates sequence by sequence. And you quickly work out that its calculation time depends on the type of robot:
You'll also notice that some robots are stored and not used.
What if you added these unused robots to increase AURA's calculation time? That would certainly save you some time!
So you have at your disposal :
sequences: sequences in place that AURA has yet to calculate
storages: other stored, unused robot ‘sequences’ that you are going to add to the existing sequences
You need to find the longest possible ‘sequence’ + ‘storage’ combination for AURA to calculate and return a result in the form: ‘sequence + longest storage’_‘total calculation time in min’.
