@Sherlock9 Way too much stack manipulation

Yeah, I never quite got the hang of stack manipulation

The key is to set up the stack in as few commands as possible so that you can do the actual operations without any intermediate manipulation (or as close as possible)

how do i clear a dom element in JS?

Yes

@Sherlock9 then do you have examples?

@Sherlock9 alright, thanks

@Mego Don't you have an operator for list of digits, base -> number?

@LeakyNun ¿ but it required the digits to be a string

@ReleasingHeliumNuclei ಠ_ಠ you dont int argc, char **argv

Hullnuts. Alright let me test that

@TùxCräftîñg *argv[] masterrace

9:03 AM

the correct form is **argv

and btw you should always include these arguments, even if you dont use them

gcc throws a warning if i don't use them :|

warnings = nobody care

distracts me

there is a argument to disable a specific type of warning

and every codebase have warnings on compilation

Helps me if i have a unused variable, but arg{c,v} is distracting

9:06 AM

so, use cmdline arguments ¯\_(ツ)_/¯

because reading the file from stdin is a bit weird

reading from file is better

[3, 2, 1]
[5]
23

Anonymous

@Sherlock9 Well, clearly there's some disparity between the trivial [5][3,2,1]+ and your full program. I'm asking, can you remove the extraneous bits of your program to just get the erroneous part?

Looks like it is generator problem indeed

9:18 AM

@LeakyNun link haz 424

I added a debug before the concatenation

@ReleasingHeliumNuclei speak in English; I don't understand

YO

@LeakyNun the link i put has the number 474, not 23

@ReleasingHeliumNuclei you didn't press save so it's 23, click on it yourself

Okay, how's this? actually.tryitonline.net/…

@Sherlock9 same problem

@LeakyNun oh

The stack before the concatenation is [5] range(3, 0, -1) 5

@LeakyNun íu will return a positive integer if it's in the iterable and 0 otherwise

@Mego I take it as a no

Anonymous

9:41 AM

No, it's a yes. It's just that í returns a 0-based index and -1 if not found, so the u is needed to convert it to 1-based and 0 if not found, for proper truthiness.

So I used í and g since, when both conditions were fulfilled, they would return -1 and 1, respectively. This is the only time when their sum would be falsey 0, so I used that to quit the loop. If you have other suggestions, I'd love to hear them.

This challenge is inspired by an earlier challenge, also by me. Your task: Input: A single unicode character, eg: a or A or ! Processing: For the input character: ** Get the unicode representation (eg: U+xxxxx) ** Get the html entity (hex) ** Get the html entity (decimal) ** Find all...

** Find all the numbers in the above three representations.

** Put them in a list, without any commas, spaces, etc.

** Add +&# to the list.

How so?

Or you didn't bother to read it?

Get the unicode representation isn't magic or science.

what do you mean by Get the unicode representation (eg: U+xxxxx)? the entire string (U+DEAD) or only the codepoint (DEAD)?

The entire string, as the example shows.

Oh my god

Did you see it now or do I need to zoom it?
