Why I get wrong answer

Code: Select all

thanks! brianfry713.I got accepted. I finally know that Null is very important for string.

[brianfry713]

Add this before line 133: compare1[new_length] = compare2[new_length] = '\0';

You can see reason of CE here in My Submissions:
http://uva.onlinejudge.org/index.php?op ... n=13999115

It is because of strlwr.

I don't think either of those functions are part of the ANSI standard, so you might not have them depending on which compiler you are using.

Maybe Judge's compiler doesn't have it.

You can do your own strlower

Code: Select all

#include <ctype.h>
char* strlower( char* s )
{
  char* p = s;
  while (*p = tolower( *p )) p++;
  return s;
}

Don't forget to remove your code after getting accepted.

Thanks a lot. After using userdefined function for that it is ACCEPTED. Thanks.

Removed after AC!!! 
For other: DON'T USE strrev();

[brianfry713]

You can see the reason for your CE by clicking "My Submissions".

Don't use strrev()

[bgcsaif]

Thanks. . . . I didn't know using strrev(); cause CE. . . . Just did it manually and it is done! but feeling upset for this problem I had nearly 9 wrong attempt on UVA!

[iliketocode]

Not too sure why i keep getting WA.... hope someone can help me resolve this

Code: Select all

#include <stdio.h>
#include <string.h>
#include <ctype.h>
#define MAX 1000

int main(void){
	char palindrome[MAX + 1] = {0};
	int len, i, j, alpha;

	while(fgets(palindrome, MAX, stdin)){
		alpha = 0;

		len = strlen(palindrome);
		if(palindrome[len - 1] == '\n')
			palindrome[len - 1] = '\0';
		len = strlen(palindrome);
		
		if(strcmp(palindrome, "DONE") == 0)
			break;
		
		for(i = 0; i < len; i++)
			if(isalpha(palindrome[i]))
				alpha++;

		for(i = 0, j = len - 1; i < alpha/2; i++, j--){
			if(isspace(palindrome[i]) || ispunct(palindrome[i]))
				++i;

			if(isspace(palindrome[j]) || ispunct(palindrome[j]))
				--j;
			
			if(toupper(palindrome[i]) != toupper(palindrome[j])){
				printf("Uh oh..\n");
				break;
			}
		}
			
		if(i == alpha/2)
			printf("You won't be eaten!\n");
	
	}
	return 0;
}

Try to check input in this thread before posting.

Try this testcase :

yours : not palindrome.

Hope it helps...
