Challenge 9’s Gotcha requires manual purchase of dimensions in a non-intuitive setting. I wrote a python script to map the list of which dimensions to buy, and how many of them to buy in what order. This guide contains that output and instructions on how to read it.
Guide to Tickspeep Upgrade
How to read a shopping list
This guide is intended for use in scientific display mode:
Each line is a series of purchases at the end of which you must check the lowest remaining price for any of the 8 dimensions and tick speed upgrades to this new lowest one.
This list isn’t perfect, it will still cause some price hikes, some because it’s unavoidable, some because I wasn’t careful enough. But here is the list quite well.
The first line reads “[[5, 17], [3, 9], [1, 4]]” translated:
- Buy Dimension 5, unless you have 9 Dimension 5’s cost 1e17 (don’t buy the 10th which increases the cost).
- Then ‘buy dimension 3, until you have 9 dimension 3’s worth 1e9 (don’t buy the 10th which increases the value).
- Then ‘buy dimension 1, until you have 9 dimension 1’s worth 1e4 (don’t buy the 10th which increases the value).
Finally ‘Buy ticker upgrades unless doing so forces a dimension price conflict’ (for line 1 this is not ‘do nothing’ as the smallest ticker upgrade is e3, which that is below the e4 currently showing for dimension 1.)
This will be impossible because Dimension 5 is locked until you buy Dimensions 1,2,3 and 4. So the instructions say ‘buy up to 9 of each dimension when you have the funds.
Also note lines 4 and 5 which read:
- [[6, 23], [1, 13], [2, 10]]
- [[3, 19], [2, 14], [1, 10]]
Where on line 4 you buy dimension 1 until you have a value of 1e13 of 9, but then on line 5 you buy dimension 1 until you have a value of 1e10…. Yes… I was too lazy to remove all redundant calls (I removed redundant calls to buy for the same purchase lines, there were a lot of them). Just ignore the instruction.
Set note 3″ at the end of the instructions [1, 7]” is when you first purchase the ticker upgrade to e4. The ticker will show e5 to buy the upgrade, but you can’t show it yet, as it will then show e6, and conflict with Dimension 2 which still costs e6.
Shopping list, good luck
My version derived from the original code is below, but Jonny improved it (I think, I didn’t test the new version. It’s probably better that my version was just good enough to pass the challenge then I left to fix it). The first shopping list is theirs.
