That is not supported by the C language version judge's gcc takes in. Put the

int k;

part somewhere at the top where you declare your variables and see if it works or not.

I'm trying to solve the problem 102 and I am having a problem.

I think my program is right, giving the correct answer in a good time without too much memory but i just get WA.

Please someone help me, this is the input that im testing:

1 2 3 4 5 6 7 8 9
5 10 5 20 10 5 10 20 10
0 0 0 0 0 0 0 0 2147483648
2147483648 0 0 0 0 0 0 0 0
0 2147483648 0 0 0 0 0 0 0
0 0 2147483648 0 0 0 0 0 0
1 2 3 4 5 6 7 8 9
1000 200 1500 350 5000 1000 1000 2000 13000
5 10 5 20 10 5 10 20 10
60 20 1000 1000 60 20 10000 20 500
20 1000 50 2000 50 500 1500 20 3000
20 1000 50 2000 50 5000 1500 20 300

and this is the output:

BCG 30
CBG 50
BCG 0
BCG 0
GBC 0
CBG 0
BCG 30
BCG 6050
CBG 50
CGB 1620
GBC 2140
GCB 2440

Can anyone tell me what is wrong with it?

Posted: **Sun Mar 26, 2006 9:03 am**

I ve got AC.

I thought the final output should be in the order BGC,BCG,GBC...CGB, but its alphabetically... but now the problem is ok.

Posted: **Mon Apr 17, 2006 10:12 am**

Could you please tell me what problem is on my code?

Code: Select all

#include <iostream>
#include <string>

using namespace std;

int take( int n, string* str, int* b, int sum )
{
    switch( n )
    {
        case 1:
            *str    = "BGC";
            return sum - b[ 0 ] - b[ 4 ] - b[ 8 ];
            break;
        case 2:
            *str    = "BCG";
            return sum - b[ 0 ] - b[ 5 ] - b[ 7 ];
            break;
        case 3:
            *str    = "GBC";
            return sum - b[ 1 ] - b[ 3 ] - b[ 8 ];
            break;
        case 4:
            *str    = "GCB";
            return sum - b[ 1 ] - b[ 5 ] - b[ 5 ];
            break;
        case 5:
            *str    = "CBG";
            return sum - b[ 2 ] - b[ 3 ] - b[ 7 ];

            return sum - b[ 2 ] - b[ 4 ] - b[ 6 ];
            break;
    }
}

int main()

    int b[ 9 ];

    while( cin >> b[0] >> b[1] >> b[2] >> b[3] >> b[4] >> b[5] >> b[6] >> b[7] >> b[8] )
    {
        int move    = b[0] + b[1] + b[2] + b[3] + b[4] + b[5] + b[6] + b[7] + b[8];

        int     small   = -1;
        string  str;

        for( int i = 1; i <= 6; ++i )
        {
            int s;
            string  s2;
            s   = take( i, &s2, b, move );

            if( s < small || small == -1 )
            {
                small   = s;
                str     = s2;
            }
            else if( s == small && s2 < str )
            {
                str = s2;
            }
        }

        cout    << str << " " << small << endl;
    }

    return 0;

since u've solve it can you actually help me with something? im running your test case, did you submit your program in the format:

input
input
output
output

or

input
output
input
output

i think mine is right but im getting WA
if you submited as the 1st one, does it end with a "end of line"?

EDITED: nvm, i found out how it works now.

This is the cause of WA.
This should be changed,
Code: Select all
while (scanf("%d %d %d %d %d %d %d %d %d", 
			&data[0],&data[1],&data[2], 
			&data[3],&data[4],&data[5], 
			&data[6],&data[7],&data[8])==9) {...

so according to this.... the process goes:

input
output
input
output
input
output

am i right?
is there an end of line at the end? must be unless u bother to check where's the last line and output without endl/println

Hi XOPHT

I tried your code. It works fine on sample input. Could you figure out the problem. I think it is quite well written.

Posted: **Mon May 29, 2006 7:06 pm**

here's the code...........

Thanks for any help.

the code is removed after getting AC

#include <stdio.h>
#include <string.h>

Code: Select all




for(i=0; i<N; i++)
		{			if(allcomb[i]<min)
			{
				strcpy(glass,col[i]);
				min=allcomb[i];			
			}
			else if(allcomb[i]==min)
			{
				if( strcmp(glass,col[i])==1) 
					strcpy(glass,col[i]);
			}
		}
		printf("%s %ld\n",glass,min);

Hi, ayeshapakhi.
I think the cause of WA is your strcmp usage.

Please change to
strcmp(glass,col)>0

Best regards.

Dear group,
I am beginner and I will be happy if some body
define the term "minimize the number of bottles that are moved".

I get different answer when the arrangement of the bin is subtracted
with the total number of bottle taking all the 3 into account. Is that
what they mean by movement of bottles. Pls help. thanks
