This part of my code will be....

Code: Select all

``````else if(coeff[i]<0)
{
if(k==0)
printf("-");
else
printf(" - ");
coeff[i]=coeff[i]*(-1);
if(coeff[i]!=1)
printf("%dx",coeff[i]);
printf("x");
k=1;
}
``````
This

Code: Select all

``````else if(coeff[i]<0)
{
if(k==0)
printf("-");
else
printf(" - ");
coeff[i]=coeff[i]*(-1);
if(coeff[i]!=1)
printf("%dx",coeff[i]);
else
printf("x");
k=1;
}
``````
Just a missing of ELSE ! Oh God... I sufferd almost for 3 years with this mistake. No one could give an input like 0 0 0 0 0 0 0 -2 0 ... huh...

Thanks Roby. Thanks a looooooooottttttttttt.

You're printing an extra space at the end of line when the coefficient of 0th degree x is 0.

i have changed my code a bit but still PE ...

Code: Select all

You've taken care of the last co-efficient only. What about others? Try to output the following input in a file and you wiil see trailing space from 3rd line onwards.

Code: Select all

``````1 1 1 1 1 1 1 1 1
1 1 1 1 1 1 1 1 0
1 1 1 1 1 1 1 0 0
1 1 1 1 1 1 0 0 0
1 1 1 1 1 0 0 0 0
1 1 1 1 0 0 0 0 0
1 1 1 0 0 0 0 0 0
1 1 0 0 0 0 0 0 0
1 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0``````

Output of

Code: Select all

``0 0 0 0 0 0 0 0 -1``
should be

Code: Select all

``-1``
Don't forget to remove your codes once you get accepted.

thanks a lot !!!!! this problem set had a lot of tricky inputs . but i got AC in 0.500. wat method have you used to solve this prob ????

My code is much shorter than yours. But it ran longer. That is because I used abs() function a lot.

Posted: Tue Dec 27, 2005 2:10 pm
wat is the method to shorten the code ?
it was frustrating to write such a big code for a problem that seems to be quite simple ### 392 CE plz hlp me
