Well, English is not my native language, but I think I am quite good. Perhaps I am mistaken, but it seems to me that the question is grammatically incorrect. Is it possible to say "The following function tests its input is what?"
Honestly, I don't understand what this is supposed to mean.

It spoils the challenge. Everyone can see it.
You should delete it as soon as possible.

Edit: Thanks.

The actual answer to the question has been posted already. I only helped with the wording. If at all, this challenge has been given away already.

In my opinion, the wording should be changed. I agree that it can be very confusing for non-native speakers, and I don't think it's in the spirit of these challenges to test for English language abilities (there are already enough of them among the crypto challenges).

I recognize that it's very hard to test for an answer to this challenge, but "blank of blank" is just too weird. At least go for something along the lines of "? of ?" with an explanation to insert some word for the question marks.

If you know the & operator, this is trivial. But as I'm not native English speaker, I still don't understand 'blank for blank'. ... so could anybody tell me what the answer is in private message? I'll appreciate it.

To avoid server pounding, after trying a challenge 10 times, you must wait 30 between tries. (Your last try was 10 sec(s) ago.)

30 what?

Can't get it, too. I know what this function does but i don't know how to explain it with 3 Words in that ? of ?-Format. Unfortunately english is not my native language. Really frustrating. The answer are really just 3 words?

Edit: OK, got it. Really just 3 words.

Hi,

Code: Select all

bool testIt(int x) {
	bool returnW;
	int y = x - 1;
	returnW = (x & y);
  return (returnW == 0);
}

is this the same?

I still have no idea, can someone help me and look at my thoughts?

Hi, I think I know what this code does - actually I'm not finding the right words for it.... can I send my idea to somebody - so that I get the right words?
thank you...

"blank of blank" says the answers "half of 42" or "primefactor of 3462234" would be valid.
(in fact, they are not. but maybe this was your problem.. write a pm if you are still in trouble)

Another tip to solve this one is to look at the code. Think about what it does. If you know what it does, you should know what means what in english. My main Problem was, that my english isn't 100%. Even though I knew all needed word's, i didn't get it for a day or two.

bottomy · Post by **bottomy** » Tue Aug 11, 2009 8:09 am

hmm im a little confused about what to write for the answer. i think i understand what its doing, like say x = 100
then (100 & (100 - 1))
(100 & 99)
1100100 & 1100011
= 1100000 = 96

but its testing to see if it will equal 0, so are we meant to find what x should be to equal 0 (which i've done). then if so i don't really get how im supposed to write it like i know the examples karma-fusebox gave, but i guess im not understanding exactly whats happening. so any clues where to look from here to find what its to do with or something?

Hey Guys,

can anbody help me, as I cant get the right wording...
I know what the code does and when it is true, so all missing is the answer...

I tried *** of (a number) and think that (a number) is correct, but im not sure what to write for ***...

I am an german native speaker and tried to translate the german word for it into english, but it was wrong...

Id appreciate help via PM!

Thanks!

The powers that be wrote:Write your answer out in words please (format: 'blank of blank')

I can see why this would be a problem for non-native English speakers, maybe a thesaurus would help you find synonyms of the word you have
