I should really get around to making that site thing with the wiki and symbol search built in to the interpreter lol

CMC: Given a rectangular matrix of size at least 3x3, remove the first and last row and first and last column.

1 2 3 4
5 6 7 8
1 2 3 4
5 6 7 8

=>

6 7
2 3

I have 5 bytes (13c00c04ec385a3a84654ddebfc86112)

13C00C04EC385A3A84654DDEBFC86112

Yup.

yay

CMC: Given a rectangular matrix of size at least 3x3, set all cells other than the first and last rows and columns to 0

also is this for solving my challenge :P

It's not necessarily for solving your challenge, these are just nice subtasks

@HyperNeutrino ... We could have done ḊṖZḊṖ instead...

true

@Mr.Xcoder no

When used as a full program, yes.

that leaves the output transposed

?

Oh right

xd

I used an example that was invariant under transposing

Namely [[3, 4, 5, 3], [3, 1, 2, 3], [4, 2, 1, 3], [4, 3, 6, 5]] xD

I'll get back to your CMC shortly, I am trying to finish my solution to your challenge :D

ok :P

many of these cmcs would fit well as apl cmcs

yes

@HyperNeutrino 9 bytes, 8343E5AF7C41148E51A6E08E793D4E21

@HyperNeutrino aren't all matrices rectangular :P

^

> rectangular

I'm a moron

I just copied the first part of yours :P

there are matrices with different sized rows

they might not be "matrices" by some definitions though

> In mathematics, a matrix (plural: matrices) is a rectangular array ... (Matrix (mathematics))

> in mathematics

ಠ_ಠ ok let's stop this terminology nonsense :P

ok :P

overly specifying something that could be otherwise taken as ambiguous doesn't hurt (unless you go way overboard)

solve cmc

:P

anyway

I'm not sure if my solution is valid yet, but I have 38 bytes for your challenge

ooh

BTW your CMC isn't actually a subtask for my challenge

Ik

ok

Writing test suites in Jelly is a complete pain

yes

Edit: I am rewriting my solution completely because I think I can shave off bytes

ooh cool

I should try solving it in Jelly

Turns out my solution is faulty

Fails for

1 3 1
3 1 3
1 3 1

oof

@HyperNeutrino Shouldn't ^^ be falsy though?

Because 1 is not strictly greater than 1.

Or am I misunderstanding

well then n=2

@HyperNeutrino What?

Is 3-3-3-3 considered a ring?

yes

Oh

because it's edge-wise connectivity for the non-mountains

so corner-wise connectivity for the mountains

Then I misunderstood it completely

rip

In fact I just have to remove some corners, I think.
