444 - Encoder and Decoder - PE Issue

See this thread: http://online-judge.uva.es/board/viewtopic.php?t=3603 I had a PE for this problem 3 years ago which was never resolved, and now I am convinced that the judge output might not have a newline character after the last line of output. Shouldn't there be a newline character after the las...

Did you notice the yellow tick before the problem? This means that there can be more than one possible correct minimum sequence.

Now please remove your ACed code as it is a spoiler.

I am also having a problem with this problem as well. Add to that problems 444 and 445, though my 445 code has been rejudged to be AC, I believe problem 444 also has judge data where the output does not end with a newline.

A reply after more than 3 years. However please check the bug and suggestions forum regarding problem 445. Thanks for the input for problem 444. I will check it out when I have time.

One other thing to add. I am seeing the best CPU for all the problems I have solved as 2.453s. Is that a bug or something?

I am certain that judge data for this problem does not have sets that have repetition of elements as my AC code does not take care of that.

Also, I think Theorem is right. Have a look at these two articles:

Why are you reading from a file? You should be reading input using cin or scanf for C++ code.

You can use sqrt(3.0).

For your second question, I don't get your question. Could you rephrase? Thanks.

For the first code, other than the problem spotted by the previous poster, this line of code also has a problem: cout <<setprecision(3)<<fixed<<showpoint; iomanip library is not well supported by the g++ compiler in the OJ. Change to this instead: cout << setprecision(3); cout.setf(ios::fixed | ios:...

Re: I need some IO :)

Hi, I 've implemented dijkstra algo. with binary heap and want to check whether it produces correct answer... so, I try 423 and get WA :( I need some tricky IO on this problem... thanks. [EDIT] My implementation of Dijkstra is okay, it was a silly mistake on the input part. :oops: , AC now :D I use...

The posted code above is fine. My AC code uses a char array of 1200000 characters and iterates through each character. However, check this: for(i=0;i<strlen(kata);i++) You are calling strlen for each iteration of the loop. Of course you will get TLE this way. Try something like this: int len = strle...

Intersting numorology! Road to final for Brazil looks easy. The only ever champions that they meet before final are England and France. They're the only one time winner and they won't likely pose much threat to team like Brazil that played against Japan. Argentina and Jermany meet in quarter-finals...

Hmmm... I have not used cin.ignore before. May I suggest an alternative? How about using two getlines? You can also use getline this way:

getline(cin,str);

where str is a C++ string.

One to read in the newline after the cin >> and the second one to read in the line you want.
