i made the mistake when i posted the topic

Are you sure that it was your mistake and not that your source uses ceill?
ceill is a valid C99 function and handles long double...

I'm guessed to be very near from the Accepted Answer. Please, may you help me by testing this simple input in your correct 362's implementations?

Maybe i will found my problem here. Thanks in advance.

My input is

And my output succeeded in my WA implementation:

Output for data set 1, 210 bytes:
Time remaining: 7 seconds
Time remaining: 5 seconds
Time remaining: 2 seconds
Time remaining: 0 seconds
Total time: 20 seconds

Output for data set 2, 10 bytes:

Your output is the same with my AC solution.
Maybe you should care about output formatting.

Hope it helps,

Why do you mean with 'output formatting'? Can you show me an example?

Thank you very much!

PD: Does your program finish each iteration with:

[c]printf("Total time: %d seconds\n\n",time);[/c]

or with

[c]printf("Total time: %d seconds\n",time);[/c]

I don't know if an extra /n at the end of the output will make execution fail... Thanks again

If it is a simple one more line, one less line thing, then you'd get PE.. so I think you probably have a +1/-1 bug somewhere... try posting random data of very long length.. I'll post my results and then you can compare a bit.

Thank you very much junbin. Please try this input in your 362 accepted problem.

Code: Select all

My output is the next one:

   Time remaining: 23 seconds
   Time remaining: 0 seconds

   Time remaining: 150 seconds
   Time remaining: 52 seconds
   Time remaining: 27 seconds

Output for data set 3, 10 bytes:
   Time remaining: stalled
   Time remaining: stalled
   Time remaining: stalled
   Time remaining: stalled

Thanks again!

my answer is exactly the same. :p

though you may wanna go through the spelling and stuff just to make sure.

I can't understand where is my fuc**** mistake in my solutions

My only chance is to try with large numbers as the total amount of bytes (for possible overflows). Did you realized similar tests with this problem when you was trying to get its correct answer?

I think i will let this problem as impossible for me... I will focus my time on other problems...

Thank you by the way, we will be in contact if needed with our tries...

Hey, if you have an ACCEPTED answer for this problem, please can you check this input and report its results here?

I think i'm VERY near from the correct solution, but still WA

Code: Select all

Thanks in advance! Joan

3rd data gave a very long string of "stalled"
4th data crashed my program

Output for data set 1, 500000 bytes:

Of course, i was wrong while posting my example. Sorry junbin, this is the correct one. Thank you very much for the time spent on me.

Code: Select all

And my output is the next one. For the last try, it makes an overflow, does like yor program? Thanks!!

I think set 4 caused my program to overflow and so anything after set 3 should be invalid.

I can't believe myself . . .

I get WA with;

remaintime=ceil(remainbyte/(transferbyte/5.0));
printf(" Time remaining: %ld seconds\n",long(remaintime));

I get AC with;

remaintime=remainbyte/(transferbyte/5.0);
printf(" Time remaining: %ld seconds\n",long(ceil(remaintime)));

only chainge is ceil in printf function...

What is the type of the remaintime variable?
