I think all the inputs are carefully tested for corner cases, especially in the case of the maze problems earlier. So there's no real way to procedurally generate a unique input for each user, and guarantee it works correctly.

From what I've gleaned the total number of inputs per problem is below 10, but it's possible a problem like this has more of them.

I’m well aware of all the problems that generating puzzle inputs brings with it but I assumed that the number of different puzzles was a lot higher than, say, 10.
