largest roots of cubic polynomials
Interesting problem! Evil problem! 'Simple' problem!
After I solved it, it looks so simple. Why I can not solve it for months? Well, I did get a somewhat not so useful hint from the PE forum a long time ago. One guy suggested to solve problem 318 first. (It is actually very helpful!)
Finally, something came to my mind and I found how these two problems are related to each other. There is a little bit math involved in it, but this is very popular, everyone knows about it. I learned the knowledge in high school. Well, in this problem, it is a little bit more complicated than high school math.
There is still another programming component in this problem for you to identify, this part is not difficult since some earlier problems has used it a couple of times.
If you still cannot solve this problem, please stare at the title of this problem for 1 minute.
