back to boardBe careful! Posted by Fu Dong 10 May 2005 16:31 1. in the equation a*t^2+b*t+c=0, consider this case: a=0. 2. maybe you will get two positive value of t, and you should check both of them, because the dart will go through the plane twice. I got AC after getting Crash & WA for the reasons above. Re: Be careful! I considered this 2 cases and even the case: b=0, but anyway I got WA 6 again :( Re: Be careful! t can be only positive? OMFG! So stupid mistake))) Now I've got 'AC' Thank you :D |
