271 - Simply Syntax

[mf]

Your program wrongly says 'YES' to this test:

Code: Select all

pCp

[Kire Sopov]

Thank you for the quick reply. I got an AC

Anyway, the fix is to just add the line:
else if (nValids == 0) return false;

after this line:
else if (it == ss.end()) return (nValids == 0);

in the function CheckValids() in my previous post.

Please remove your code after getting AC.

[helloneo]

Input description says..

assume that each sentence has at most 256 characters and at least 1 character

So, you may have to increase the size of the array..

AC. some of my frnds and my code has same problem. we just had to handle the case for 'N' specially. then ac. but the same condition for 'N' i gave when i checked it with other 4 char : D,I ,E, C. dont know why i get WA then.

[sonjbond]

i m getting WA
my code is here


#include<stdio.h>
#include<string.h>
int main()
{
int i,j,k,len, a,b,c,m,n,t,kase,sum;
char sen[300];
while(gets(sen))
{
len=strlen(sen);
int s=0;
int n=0;
int c=0;
if(len==1&&sen[0]>='p'&&sen[0]<='z')printf("YES");
else if(sen[len-1]>='p'&&sen[len-1]<='z'&&sen[len-2]=='N')
{
for(i=0; i<len-1; i++)
{
if(sen=='N')n++;
}
if(n==len-1)printf("YES");
else printf("NO");
}
else if(sen[len-1]>='p'&&sen[len-1]<='z'&&sen[len-2]>='p'&&sen[len-2]<='z')
{
if(len==3&&(sen[len-3]=='C'||sen[0]=='D'||sen[0]=='E'||sen[0]=='I'))
printf("YES");
else
{
n=0;
for(i=0; i<len-2; i++)
{
if(sen=='N')
n++;
}
if((sen[i-1]=='C'||sen[i-1]=='D'||sen[i-1]=='E'||sen[i-1]=='I')&&(n==len-3))
printf("YES");
else printf("NO");
}
}
else printf("NO");
printf("\n");
}
return 0;
}
