I've compared my computer with my friend's accepted program.

I found that his main algorithm is to find the maximal viewing angle between (x1,0) and (x2,0) using binary search.

But I have a random data like this

"-41 328 150 467"

my program output 0.528878 {which meet the peak value at (173.423285,0) on the right side of (x2,0)}

but his program output 0.527316 {which meet the peak value at (150,0)}

Must the programmer view the Billboard bewteen (x1,0) and (x2,0)?

If I misunderstood the description of this problem,please tell me the right one.

Thank you very much.
