Why WA? Help me to find test where I am wrong please!!!!


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

char s[1000];        /// I tried here even 1000000, but still WA
int i,j;

int main(void)
{
  while(gets(s), strcmp(s,"DONE"))
  {
     i = j = 0;
     while(s[++i])
      if (isalpha(s[i])) s[++j] = s[i];
     for(i=0;i<j;i++,j--)
       if (tolower(s[i]) != tolower(s[j])) break;
     if (i>=j) printf("You won't be eaten!\n");
	 else printf("Uh oh..\n");
  }
  return 0;
}

no test cases
Are you sure i & j ' s initial value = 0 ?

Posted: **Wed Oct 26, 2005 7:43 pm**

yes - the program works correctly on all my tests

Try this testcase :
.!?,As.,!?i I!!!,S,,a

My Acc program output : Palindrome.
yours : not palindrome.

Hope it helps...

Hey, I get WA in this problem. Can someone post some inout/outputs please?

I tested my program with this:

Code: Select all

Madam, Im adam!
Roma tibi subito motibus ibit amor.
Me so hungry!
Si nummi immunis
.!?,As.,!?i I!!!,S,,a
t
at
Madam, I adam!
DONE

Output:

Code: Select all

You won't be eaten!
You won't be eaten!
Uh oh..
You won't be eaten!
You won't be eaten!
You won't be eaten!
Uh oh..
Uh oh..

Thanks.[/code]

To Schutzstaffel:
The answers are correct.

Send me your code to my e-mail - I'll check your program.

That input also gives me correct output :?

To medv: just emailed you the code.

Thank you both.

Try this test:
aa

This is a palindrome, but your program says that no.

Thanks a lot, got AC now!

I forgot to complete that test case, I only checked if the string size was 2 but forgot to compare the chars to see if they were the same

Thanks.

empty string shoud be considered as pelindrom

Code: Select all

for(int j=0,k=strlen(pal)-1;j<strlen(pal),k>=0;j++,k--) 
{ 
if(pal[j]==pal[k]) 
flag++; 


else 
{ 
flag=0; 
break; 
} 
}

here in your code , for empty string flag =0

Code: Select all

if(flag>0) 
cout<<"You won't be eaten!"<<endl; 
else 
cout<<"Uh oh.."<<endl;} 
}

and here if flag=0 prints Uh oh..

just change those part ..
in first part
change only 1 line

Code: Select all

else 
{ 
flag=-1; 
break; 
} 
}

and second part change one line

Code: Select all

if(flag>=0)

another thing after get ACCEPTED dont forget to remove your code,

and it is a good practice to give your code in code tag
other wise it is difficult to read
