@Doorknob codegolf.stackexchange.com/q/22585/3396

The last example, are you sure that one is correct?

The first loop should imo not be jumped into.

Is there a built-in C++ function to convert, say, 97 to 'a'?

(char)number;

Now, I am trying to append a const char to a string r: r.append(s[i][2][j]);

It won't let me.

How can I do this?

Never mind again.

Use python

Or SPIN

I don't have Python anymore.

I never installed it again after I wiped my computer.

Anyway, I know C++ better.

Sort characters by darkness Your program must take as input a line of characters, like this: @+.0 And output the characters sorted by how dark they are, like this: .+0@ Requirements: You must use a monospaced font for darkness detection. You must find out how many pixels each character...

@TimWolla whoops, I will correct that

hosch250

I am almost done with my input validator.

Just removing some bugs that involve the leap year.

And making ints and doubles continue requesting input after invalid chars are given.

TimWolla

@Doorknob Still not working properly for me

Once the “big loop” finished

The next won't be entered (obviously)

Doorknob

@TimWolla heh, whoops, fixed again

TimWolla

@Doorknob Aaaaand my code passes :D

Doorknob

yay :D +1

3:10 AM

Without any change

Doorknob

btw, I count 1008 chars

TimWolla

Me too, strange

Seems I forgot to update the count after changing

I remember an issue with IO

Whatever

Let's see when I'm going to hit 500 rep

hosch250

Just have to allow the input range for types i and f and the specific input format for type s.

hosch250

5:54 AM

Done with integer input.

Hit a bump with double ranges.

stoi(string) does not support floating point numbers.

Will probably have to write one myself :(

Here is an interesting challenge:

Q: Find the smallest prime from a substring

In 1946 Erdos and Copeland proved that a certain number is a normal number, i.e. the digits in its decimal expansion are uniformly distributed. Users will input a sequence of digits and you will find the smallest prime that contains that string in base 10. Example: input -> output "10" ->...

Print Your Username This challenge is to print your own username. You can either hard-code it, or get it off the web. This may seem easy, but there is a twist: your program must only contain numbers (0-9). Shortest code code-golf wins.

Jan Dvorak

@Doorknob I'd like to check if a string is a substring of another

Doorknob

oh, then just special-case for empty string I guess?

Jan Dvorak

Not worth it, I guess, if not supporting an empty string is an option too :-)

I'm rather interested in why does it fail

Doorknob

because the creator of GolfScript was too lazy to make it work? :P

Peter Taylor

@JanDvorak The first 0 chars of a string match the empty string, so it removes them and then looks again at the same index in case there's another match there...

@JanDvorak You can check for substring with ?) if you're using a version of the interpreter which is less than 2.25 years old. I submitted the patch.

We've had a rash of bad/off topic questions lately.

Jonathan Van Matre

Meanwhile, if you judge by the Area 51 report on the site, what we need most to get out of beta is more questions.

Catch-22 much?

hosch250

Well, we've had more good questions too.

You know, having 15 questions a day would be tricky.

We wouldn't be able to do all the ones we wanted.

Jonathan Van Matre

Yeah...and I think we'd all end up maxing out our vote count easily every day.

I think SE's standards for what makes a good Q&A site just don't map to what makes a good contest site.

hosch250

Yeah.

Jonathan Van Matre

I stumbled on this thread yesterday: codegolf.stackexchange.com/questions/2070/language-choice

Jonathan Van Matre

Good question

I'll upvote it later when I can vote meta again

I think it goes hand-in-hand with the thread about changing the community name from Programming Puzzles to Programming Contests

ASCII art contests aren't very good puzzles, but they are good contests

I'll have a more fully-formed answer along those lines in a bit

hosch250

@TimWolla It is pretty good.

mniip

@TimWolla <Win>+<Enter>, V, I, M, <Enter>, I :P

hosch250

However, both your example have 10 steps.

Jan Dvorak

7:16 PM

I like "score when fed to itself"

TimWolla

@hosch250 Do they?

hosch250

The cursor should be at the end ready to type again.

TimWolla

@JanDvorak The wording of it?

hosch250

So you should add a 10 H Right.

TimWolla

@hosch250 I think it is fine that way. It is about typing exactly that text.

Jan Dvorak

7:18 PM

I'd allow P/R for a long hold

TimWolla

Makes optimizations more interesting imo

hosch250

OK, that is fine too.

Jan Dvorak

as in, type something - hold left/right - type again

Are CTRL+C / CTRL+V allowed? More generally, what is the environment? — Jan Dvorak 1 min ago

CTRL C should be allowed

CTRL is called STRG in German

How do you know what is in the clipboard?

TimWolla

7:20 PM

> The clipboard is assumed to be empty

Jan Dvorak

@hosch250 whatever you put there

TimWolla

You can mark the text using Shift + Arrows

And copy it using CTRL+C

hosch250

OK, so the clipboard is blank to begin with.

TimWolla

@JanDvorak What exactly do you mean by environment? I cannot think of anything affecting else affecting the program at the moment

Jan Dvorak

do you realise it contains unary factorisation as a sub-problem?

@TimWolla the editor being used, for example

<CTRL+H>pattern<TAB>replacement<ENTER>

TimWolla

7:22 PM

@JanDvorak Shortcuts specific to an editor are not allowed. Only the default system hotkeys.

@JanDvorak If I knew what “unary factorisation” is :)

Jan Dvorak

define "default system hotkeys". Which OS?

@TimWolla given a value in unary, factorise (express as a product of primes) the value

TimWolla

@JanDvorak The OS the answerer chooses, should it be restricted / hotkeys be whitelisted?

Jan Dvorak

In which case, let me implement my own OS, a branch of (say) Suse, that supports native search/replace in any native text field

(which would actually be cool IRL)

TimWolla

I'd say that falls under standard loopholes

“Using a made-up language specifically designed for the challenge”

Jonathan Van Matre

@Jan

bah. @JanDvorak that would be cool. why doesn't every OS have that?

Jan Dvorak

7:29 PM

I love empty pings

@TimWolla it's not specifically designed for the challenge

TimWolla

@JanDvorak Any suggestions for a wording then? You probably know the site and the culture better than me.

Jan Dvorak

@TimWolla define a set of allowed shortcuts. Search & replace would be nice, BTW ;-)

TimWolla

@JanDvorak I'll include them. I want to see interesting algorithms :)

Quincunx

How do people do these things where there answer/question has this little thing that appears? Let me try it (TimWolla's chat post is the last one to do this):

hosch250

mniip

@JanDvorak or you could make it type multiple different letters depending on how long do you hold the key, so you end up with a page of text with just a few key "strokes"

@hosch250, are you treating FORWARD commands with diagonal directions as multiplying their value by sqrt(2)? That would simplify things, but it's not very Logo-like.
