@CatWizard "The robber's code must also differs in output from the cops program for some number larger than n." what if this happens because of int overflow?

@Rod lol wanna prepare a funeral?

@Cowsquack Then that's a crack.

Oh yeah aren't overflows platform specific?

Q: Hardcoding the Cops and Robbers (Cops)

An interesting question to think about is the following: If I have a sequence of numbers how many of them do I have to provide before it is clear what sequence I am talking about? For example if I want to talk about the positive integers in order starting from \$1\$, I could say \$1,2,3, \d...

@EriktheOutgolfer I tried to make an ascii casket, but failed miserably. Then I tried to come up with a pun with comma / cremation but failed too :c

@Dennis I have an issue with Dodos: shouldn't this return (1, 2) instead of (0, 3)? also

@EriktheOutgolfer "surrender"

look at the example

Erik the Outgolfer

um, is that a pun? because "surrender" is exactly why the first one should return (1, 2) instead of (0, 3)

Cows quack

> |0 - 1| = 1 ≥ 0, so trying to compute f(1) will raise an exception, and f(0) returns its argument (0).

from what I understand, because dip'ing 0 results in a value larger than itself, dodos surrenders

Erik the Outgolfer

try removing main and you'll see that it does return (1, 2)

@JoKing I'm working on a faster verifier + some tools for programming in Lost, so hopefully the verification shouldn't be too bad.

but, since main is called with (1, 2), where (1, 2) > (0, 3), it should return its (new) argument unchanged, i.e. (1, 2)

of course, adding a dab as in my second link should make the final output be (2) (not () or (0, 3))

How do y'all keep track of so many programming languages in your head that you can read and understand them at a whim ...

Erik the Outgolfer

?

Pavel

@AdmBorkBork Well, it was made by Dennis, which automatically makes it important, and Dodos only has 3 commands, so it's super simple.

Erik the Outgolfer

that is, if I haven't caught a bug

@AdmBorkBork I looked at the readme :)

@CatWizard Did you ever end up posting? I managed to not go on PPCG for an entire week so I missed it if you did.

DJMcMayhem

@AdmBorkBork I only know the two I wrote, the two I use at work all the time, and the a couple golfing languages that I'm terrible at

Pavel

I just like learning programming languages

I don't know quite as many as Quartata, but I know a lot

Here's an interesting thing about Q#: Like F#, it has let foo = bar and let mutable foo = bar, but you can also declare a mutable variable without giving it a value, like in C#, so you can do let mutable foo;

And I think that looks a bit silly.

hi all

Pavel

Does the number 2097158 have any signficance? I just got it an exit code from dotnet.

It doesn't seem to be divisible by 256, or any kind of over/underflow...

Thomas Ward

if you look up 'dotnet 2097158' on Google you find a handful of issues in the dotnet program/repository, not sure if that's relevant here or not, @Pavel

Cat Wizard

@Pavel post what?

Pavel

Seems to be a bug in dotnet itself

A: Sandbox for Proposed Challenges

Saddle points in a matrix A matrix can be thought of as the altitudes of a surface in 3D space. Consider the 8 neighbours (orthogonal and diagonal) of a cell as a cyclic sequence in clockwise (or anticlockwise) order. Some neighbours may be higher than the original cell, some lower, and some lev...
