It's possible to make a function with no loops and no lookup tables that maps 1..8 to 1..3, 6..10 omitting 4,5

Here's the code: https://scratch.mit.edu/projects/177945410/#editor

Sorry, it was too complex to recode as scratchblocks and I think the scratchblocks generator is offline.

First I derived a function to create a 1 unit gap, and then used the output from that in another copy that created a second 1-unit gap.

Somewhat hackily derived by trial and error in this case, though it should be possible to rigorously derive these functions in the general case.

Err, you seem to have omitted 5 and 6 rather than 4 and 5.

This is the sort of thing you come across 6 months later and wonder what it does and why you did it that way! Having had programs which I've had to maintain and modify over 25 years in some cases I'd go for something I can immediately understand every time.

But obviously I shouldn't have said it wasn't possible in a single block, that was just asking to be proved wrong.

I may be being quite stupid here. Im a bit rusty on my scratch knowledge recently

secondly, this forum was about a specific randomiser which omits certain numbers, which your project does not include

you have to pur the <<pick random (1) to (3)> or (pick random (5) to (10))>

it has to be ‘or’ not ‘and’

loL you are being stupid too, no critisism though
