You are attempting to climb up the roof to fix some leaks, and have to
go buy a ladder. The ladder needs to reach to the top of the wall,
which is h centimeters high, and in order to be steady enough
for you to climb it, the ladder can be at an angle of at
most v degrees from the ground. How long does the ladder
have to be?
Input
The input consists of a single line containing two integers h
and v, with meanings as described above. You may assume that
1 ≤ h ≤ 10000 and that 1 ≤ v ≤ 89.
Output
Write a single line containing the minimum possible length of the
ladder in centimeters, rounded up to the nearest integer.
