This problem was hidden by Editorial Board member probably because it has incorrect language version or invalid test data, or description of the problem is not clear.

NOCOMMEN - No comment

Your task is to remove all comments from C/C++ program.

There are 2 types of comments:

  • multi-line: /* comment */
  • single-line: // comment

However, You have to remember about the character \ which binds two consecutive lines. For example:

// this is a comment \
that's still a comment


Program written in C/C++ with comments.

Warning: tests may contain characters of Ascii value greater than 127.


The same program but without comments.

Warning: "Exact judge" is used in this problem, so you should not ignore any whitespaces in the output.


// program which adds two numbers \
sorry... three numbers


int main(void)
int a, b, c;
a - first number
b - second one
c - last but not least
scanf("%d %d %d",&a,&b,&c);
return 0;


int main(void)
int a, b, c;

scanf("%d %d %d",&a,&b,&c);
return 0;

@Dominique: Thanks again for your supportive words here and in a few other places. I don't think calling it a race is entirely accurate, as we often do things like improving in language X even though it has no chance to beat our shorter solution in language Y (which might lead to new insights for language Y in some cases, but you know what I mean), and some other considerations. Anyway, it's cool to have top spot for a little while, until someone else decides to (re)claim it. ;)

Congrats to you too; your recent wave of Ruby submissions is quite intriguing. :) I'm sure you'll find more improvements too.

@Mitch: Wow! You are now the 1st one, beating legendary Jander after a very hard race with Linghui Liu. Sincere congratulations at you Mitch and also Jander and Linghui Liu!
It's very motivating.

Note: Tests like these do not occur in the input: (and it's not a good idea to add them at this point, because of the current AC solutions)

Also, in answer to primo's earlier question, I've checked that the C/C++ programs have properly terminated quotes and comments.

It could be helpful to include a note in the problem description that an exact judge is being used for this problem (instead of the standard "Ignores extra whitespaces" one).

Yes, it is. Good luck. :-)

And you've done it again (as I predicted on IRC)! I take it yours is based on mine as usual ?

Finally something challenging for you. :-)

@challenger - ooh, you rotter! 57 in Perl indeed.

Needs rejudge, my 130 Python solution is invalid in Python 2.7.
