1.0) Subtraction *
I have 180 points for Subtraction too. I'm starting off with relatively easy problems. I'll put another 3 or 4 up soon but I'm thinking about Triples right now.
People posting solutions here is inevitable so don't worry too much about it. I'll refrain from posting solutions as a courtesy and I appreciate your efforts in this vein.
I've put up 6 problems now and am done for now. The difficulty will keep increasing, don't worry.
On Anyway: Perhaps different words would make the pattern easier to find (I could add
With your hint I was able to find the pattern in Anyway, and come up with a 161 point solution for it! (Or 174 points by cheating.) Now all that remains is to optimize it...
And, have a 160 point solution for Addition.
Edit: Made a solutions gist so I don't have to post spoilers here. Solved up to Typist so far.
Good idea on a separate solutions gist, I'll join you there and try to use this gist for problem construction and related ideas.
Do you think I should change the strings for Anyway to make the pattern easier to see? or would that spoil the fun. I'd like the puzzles to stretch people in different ways: some to test people's ability to find patterns; some to test people's ability to code them; some to test people's golf skills.
I like Typist. It's a nice easy-level problem. Maybe you should move it upward, next to the easier ones, but the trick involved in shortening it is pretty neat.
Maybe instead of adding both "banana" and "eleven" to the left side of Anyway, you could add only one of those?
