back to boardNo AC since 19-Feb-2002 (Even program that got AC on 18-Feb-2002 gets now WA) Re: I agree with you.
I am trying to get AC.. all possible ways;
It is obvious that the solution uses Horner's scheme
the output is ambiguous: for example
for n = 2 the following two outputs are correct:
2
1
0
*
X
+
*
X
+
0
X
*
1
+
X
*
2
+
so which one to output ? I've tried both but WA;
I really think the admins should recheck this problem's tests..
and clarify the problem's description.
Could admin give a reply??? Now maybe no one know hot to solve this problem. Posted by aaakkk 28 Mar 2002 19:23 Admins rarely reply here.... send'em mail to acm@timus.ru > Re: Those outputs are wrong. For instanse, your first output written in usual way looks like that:
2*(1*0+X)+X that is equal to 2*1*0+2*X+X I don't think it resembles
the true output very much.
