Dominik: I print them and get accepted!
I was in doubt when I reviewed my code for my post in this thread, but I rechecked it, and it is so. Not even P.E. but plain AC.

Hmmm, that's strange ....
If I correct remember statements say, that spaces at end of line should be avoided .... (I got P.E. - maybe instead of that ?)

Sorry to interrupt, but I just last my WA's by replacing NULL string '\0' with whitespace...
They really make me think that they ARE right, Dominik!
Thank's to Hisoka and Little Joey...

I got Wrong Answer
but I don't know why ><...

[cpp]
#include <iostream.h>
#include <string.h>
#include <stdio.h>

int main()
{
char data[101][101];
int msize;
int n,t,t2;

for (t=0 ;t<=100 ;t++)
data[0][t]=' ';

n=0;

// freopen ("482in.txt","r",stdin);

msize=0;
while (gets (data[n]))
{
if (strlen(data[n])>msize)
msize=strlen (data[n]);
n++;
for (t=0 ;t<=100 ;t++)
data[n][t]=' ';
}

for (t=0 ;t<msize ;t++)
{
for (t2=n-1 ;t2>=0 ;t2--)
cout << data[t2][t];
cout << endl;
}

return 0;
}
[/cpp]

Thanks!

your output:

should be:

"I think, therefore I am."

Try to rotate strings four times, they should be like they were in the beginning...

Hello!

I've tested your program and found that it suffers from Presentation Errors. So I would suggest the following modifications:
1. Delete line 46: intLines += 1;
2. Delete line 72: if (I != intLongest - 1)

Try it and get AC!

i adjusted what u have told about my program . i printed a space instead of continuing when the string length is small . my program now prints the same as the sample out put of urs. but still having wa.

.plizzzzzzzzzzzzzz help me .

here is my code :

Code: Select all

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

#define row 100
#define col 110

char input[row][col];
int index=0;

 int max_count(){

	int i ;
	int max=0;
	for(i=0;i<index;i++){
	
		if(strlen(input[i])>max){
			max=strlen(input[i]);
		
		}
		else
			continue;
	}

	
	return max;

}

void print(int max){

	int i ,j;

	for(i=0;i<max;i++){
	
		for(j=index-1;j>=0;j--){
		
			if(i>=strlen(input[j])){
changed here!!--------------------------------------->printf(" ");
/**************************************************/
				//continue;
			}
			else
				printf("%c",input[j][i]);
		
		}
		printf("\n");
	}

Why WA?
I've ever looked all posts about this problem, but none helped me.

[cpp]
#include <iostream.h>
#include <string.h>

void main()
{ char matriz[102][102];
int cont, max;

cont=0;
max=0;
while (cin.getline(matriz[cont],100,'\n'))
{ if (strlen(matriz[cont])>max) max=strlen(matriz[cont]);
cont++;
}

for (int i=0; i<max; i++)
{ for (int j=cont-1; j>=0; j--)
if (strlen(matriz[j])>i)
cout << matriz[j];
else cout << " ";
cout << endl;
}

}
[/cpp][/code]

Here is my code... i tried to substitute '\0' in the array "str" with spaces but i still get WA. I saw some topics about 490 but i didn't found where i'm wrong... can you help me?

[c]
#include <stdio.h>
#include <string.h>

main()
{
char str[103][103]={'\0'};
int i=0,j,maxl=0,k,pos;
while( fgets(str,102,stdin) )
{
pos=(strlen(str)-1);
if (pos<0) pos=0;
if (str[pos]=='\n') str[pos]='\0'; /* Erases fgets' '\n'*/
if ( maxl<strlen(str) ) maxl=strlen(str);
++i;
}
--i;

for (k=0;k<maxl;k++)
{
for(j=i;j>=0;j--)
{
printf("%c",str[j][k]);
}
printf("\n");
}
}

[/c]

Thanks in advance!

I don't know where is wrong~~
Could anybody help me???
[c]#include <stdio.h>
#include <stdlib.h>

int main(void)
{
int i=-1,j=-1,k,l,max=0;
char ch[105][105],a;
while(scanf("%c",&a)!=EOF)
{
i++;
j=-1;
while(a!=10)
{
if(a!=9)
{
j++;
ch[j]=a;
}
scanf("%c",&a);
}
if(j>max)
max=j;
}
for(l=0;l<=max;l++)
{
for(k=i;k>=0;k--)
printf("%c",ch[k][l]);
printf("\n");
}
return 0;
}[/c]

Posted: **Sun Oct 31, 2004 9:57 am**

in printing section add this code:

Code: Select all

for(k=i........)
{
      if(ch[k][l]<='\0')
         ch[k][l]=' ';
      printf(.........);
}

and make your array size little bigger

Note: problem statement is false, about input size!!
