Let me give you a hint to reproduce the “Repeat” feature using a lunchbox.
Let’s take a look at this lunchbox:
This looks really complicated…
Now, here’s a question: What happens when you run it?
Well… there’s no way I can figure it out in my head. It’s too complicated.
I figured it out! I think the result will be a lunchbox that can be converted to .
Correct. Saya, You’re exactly right!
What? How is it possible that you figured it out so quickly?
Saya, did you solve it all in your head?
Not really. Actually, I used a trick. Let me explain.
First: Take a look at the top section.
Oh! The top section is actually a lunchbox that can be converted to .
Yes. So we’ll replace this section with .
Second: Take a look at the middle-right section.
The middle-right section is actually a lunchbox that can be converted to .
Yes. So we’ll replace this section with .
I see…
Now, take a look at this section.
This looks like Saya’s lunchbox that can reproduce the “Plus 1” feature .
Exactly. So we’ll replace this with .
Hmm… it’s getting much simpler.
Finally, take a look at the bottom-right section.
Oh! This looks exactly like the one we saw on the last page: a lunchbox that reproduces the “Conditional” feature .
Exactly. So we’ll replace it with the “Conditional” feature .
Here’s how we’re going to replace it:
After the replacement, it’ll look like this:
Wow, it’s much simpler now!
Let’s run it. Press Run !
From here, it’s simple.
Press Run !
See, the final result is .
Hmm… You’re right.
But… isn’t that cheating?
Saya’s method was to replace each section with the corresponding mathbox features…
But I’m wondering: Would the result also be if we run the original lunchbox directly?
Let’s check!
Let’s run the original lunchbox directly.
