Discussion of Problem 1093. Darts

Be 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.
