At sea level, atmospheric pressure is 100 kPa and water begins to boil at 100°C. As you go above sea
level, atmospheric pressure decreases, and water boils at lower
temperatures. As you go below sea level, atmospheric pressure increases,
and water boils at higher temperatures. A formula relating atmospheric
pressure to the temperature at which water begins to boil is
$$ P = 5 \times B - 400 $$
where \(P\) is atmospheric pressure measured
in kPa, and \(B\) is the temperature at
which water begins to boil measured in °C.

Given the temperature at which water begins to boil, determine
atmospheric pressure. Also determine if you are below sea level, at sea
level, or above sea level.

Note that the science of this problem is generally correct but
the values of 100°C and 100 kPa are approximate
and the formula is a simplification of the exact relationship between
water’s boiling point and atmospheric pressure.

\(B \geq 80\)
\(B \leq 200\)

The input is one line containing an integer \(B\) where \(B \geq 80\) and \(B \leq 200\).
This represents the temperature in °C at which water begins to
boil.

The output is two lines. The first line must contain an integer which is
atmospheric pressure measured in kPa. The second line must contain the
integer -1, 0, or
1. This integer represents whether you are
below sea level, at sea level, or above sea level, respectively.
