[VicPiMakers Projects] Jims challenge in google sheets + a bit of javascript in google apps

[George Bowden]

Hi Michelle
We are looking for the simplest deterministic rule to generate the output
from the input.

This is like those "what's the next number in the sequence" quizzes.  So
the following is a rule that can generate a conforming output:
"take the first number x, move right x times, print it 3 times, increment
x, move right x times, print it one fewer times, print "#repeats, list"
So there are multiple correct answers. But Greg's answer has the advantage
that it can be applied to any list of numbers, even  an empty list, and it
is built from relationships between numbers, not constants like mine.  He
just needs to print ", #repeats, list" at the end of his output.

It depends on whether one applies

   - deductive,
   - inductive,
   - abductive,
   - reductive,
   - fallacious,
   - legal, or
   - Trump reasoning (just to kick the discussion off ).  Lives depend on
   it.
