I've also got WA three times..
No idea why.
I tried to output all the result at once...
I think I've put the blanks correctly... Plz help...
Thanks in advance...

Code: Select all

removed after ac

The outputs of two consecutive cases will be separated by a blank line. You are both printing too many blank lines.

For the 7th time got WA. Tried every way printing line(Two consecutive outputs & after or before last or first output) /not printing either way. Now i am helpless...........

Code: Select all

#include <stdio.h>
int main()
{
    int a,b,c,d,k,m=0,n,i,j;
    int arr[1000];
    scanf("%d",&a);
    for (i=0;i<a;i++){
        //printf("\n");
        scanf("%d",&b);
            c=0;
            d=0;
            k=b;
        for (j=0;j<b;j++){
            scanf("%d %d",&c,&d);
                    n=c-d;
            if(n<0) n=n*(-1);
            arr[j] = n;
        }
    }
    for(i=0;i<a;i++){

            for(j=0;j<k-1;j++){
            if(arr[j+1] != arr[j]) m=1;
        }
        if (i>0) printf("\n\n");
        if(m==0) printf("yes");
        else printf("no");

The last code that you posted isn't printing a newline char at the end of the last line. You are printing: "yes\n\nyes"

I submitted as you said but I still got a WA... What should I do...

Code: Select all

removed after ac

Posted: **Thu Jun 26, 2014 8:01 pm**

Now you're printing too many blank lines.
Remove line 12: cout << endl;
Change line 27 to: if(i!=0) cout<<endl;

Posted: **Fri Jun 27, 2014 9:11 pm**

Still no luck..!

I've removed the 12th line and also changed the 27th line as you said.
by the way, the question said that there has to be blank line between each input. I think removing the 12th line won't satisfy that condition...

Code: Select all

removed after ac

Posted: **Mon Jun 30, 2014 9:24 pm**

wooh.. I got AC. I made a silly mistake last time. Thank you brianfry...
