[mmonish]

ur output format is not correct. ur output format should follow the output specification.Here u can output like this

Code: Select all

cout << str1 << " (to " << str2 << ")" << endl;
cout << "eu        " << s << endl;
cout << "tu        " << s << endl;
cout << "ele/ela   " << s << endl;
cout << "n" << c <<"s       " << s << endl;
cout << "v" << c <<"s       " << s << endl;
cout << "eles/elas " << s << endl;

You must print a blank line between the output sets , not after each output sets.
Hope this helps.

[fuad420]

hi mmonish,
Actually i gave all the blank spaces properly as you mentioned. that means my output format is exactly like

Code: Select all

cout << str1 << " (to " << str2 << ")" << endl; 
cout << "eu        " << s << endl; 
cout << "tu        " << s << endl; 
cout << "ele/ela   " << s << endl; 
cout << "n" << c <<"s       " << s << endl; 
cout << "v" << c <<"s       " << s << endl; 
cout << "eles/elas " << s << endl;

but i am not sure why my code is not showing those blank spaces in the electronic board!!! in the board its not showing any blank spaces after
eu, tu, ele/ela...... that's funny,isn't it?

Actually mmonish i am not getting your line

You must print a blank line between the output sets , not after each output sets


would you plz explain it more? here i am not sure which segment is output sets? i think for each input there is a output, and this output is a set,isn't it? like the output generated for "falar talk" is an output set,am i right? i am confused where to place blank line. plz help. Thanks.

[mmonish]

u have to print a blank line after each test case but not after the last one.
here is an example not from the prob

Code: Select all

input
1
2
output
55

66

I hope u will get the point.

thanks mmonish. i got AC.

I suspect this is another problem where you can't get accepted with Java. I ended up writing the same program in C++ instead. Please let me know if you spot any issue with the above code or got accepted in Java. Thanks.

I am getting WA too, and I dont know why!

Look out my code:

        		flag = 1;
        	else
        		cout << endl;

		cout << portuguese << " (" << "to " << english << ")" << endl;
		
		if (portuguese.size() > 1)
		{
			tv = portuguese[portuguese.size()-2];

You can't use the "nos" and "vos" as copy-paste strings in the array. For them you have to use 243 explicitly.


Like this:

Code: Select all

for (i=0 ; i<6 ; i++) {
        if (i==3) {
            putchar('n'); putchar(243); putchar('s');
        } else if (i==4) {
            putchar('v'); putchar(243); putchar('s');
        } else
            printf("%s",t_rep[i]);
        for (j=1 ; j<11-strlen(t_rep[i]) ; j++) {
            putchar(' ');
        }
        printf("%s%s\n",str,c_rep[con][i]);
    }

I think the reason for this is that 243 falls under the territory of "unsigned char". And if you use an array for the printing process then you can't STRLEN() on them using normal array pointing (or whatever).

Another problem I'm facing is that I'm getting AC only when I'm submitting in C++. In C, the same code is giving PE.
EDIT: Now I got AC in C too. The Unsigned Char issue is the thing. And strlen() can't calculate properly if string contains Unsigned Char.

Tip 2: I don't know Java that well to debug your code. Not even what I'm talking about. But is there something like unsigned char and char difference in Java? If so, then the string length calculation is bound to fail. In my case that's what happened. I assigned like this:

Code: Select all

unsigned char t_rep[6][30]={"eu","tu","ele/ela","nós","vós","eles/elas"};

While printing, I printed all the string using loop even the nos vos. I got WA
Then I used the exceptions n243s and v243s but still WA
Then

Code: Select all

char t_rep[6][30]={"eu","tu","ele/ela","nós","vós","eles/elas"};

Which is totally illogical so WA
Then I did

Code: Select all

char t_rep[6][30]={"eu","tu","ele/ela","nss","vss","eles/elas"};

Did the strlen() on these and the exceptions too were used. AC.

I think strlen() has some prob with that or something. Hope this info helps. I understand how damn frustrating it can get.

Tip 1: Test these

Code: Select all

I see what you mean - that the English word doesn't necessarily start one space after the Portuguese word. So I added a trim() function which takes out all trailing spaces (before and at the end of the string).
I still get WA.

Java doesn't have unsigned variables. I'm pretty confident the String.length() counts correctly all characters, including (char) 243.
I really appreciate your input to my problem though. Thanks.

I finally got AC with Java... (I hate this problem. )

Some things about Java:
1. In Java, char is always unsigned.

2. Java will automatically encodes the output to your default character set.
For example, "Big5" is for Traditional Chinese, "GB18030" is for Simplified Chinese, "KOI8-R" is for Russian.
I guess the most used encoding of Windows PCs is "UTF-8".
However, the on-line judge I/O is encoded in "ISO-8859-1".

For Java users, I got AC by the code like this:

Code: Select all

  StringBuffer buf = new StringBuffer();
  OutputStreamWriter cout = new OutputStreamWriter(System.out, "ISO-8859-1");
  
  // your code here
  
  cout.write(buf.toString());
  cout.flush();

Thank you annhy, my solution was finally accepted.

This shouldn't be an issue at all.
