At sea level, atmospheric pressure is $100$ kPa and water begins to boil at ${100}^{\circ }C$. 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

$${\displaystyle P=5\times B-400}$$

where $P$ is atmospheric pressure measured in kPa, and $B$ is the temperature at which water begins to boil measured in ${}^{\circ }C$.

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 ${100}^{\circ }C$ and $100$ kPa are approximate and the formula is a simplification of the exact relationship between water's boiling point and atmospheric pressure.

Input Specification

The input is one line containing an integer $B$ where $B\ge 80$ and $B\le 200$. This represents the temperature in ${}^{\circ }C$ at which water begins to boil.

Output Specification

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.

Sample Input 1

99

Output for Sample Input 1

95
1

Explanation of Output for Sample Input 1

When $B=99$, we can substitute into the formula and get $P=5\times 99-400$ which equals $95$. Since $95$ kPa is less than $100$ kPa, you are above sea level.

Sample Input 2

102

Output for Sample Input 2

110
-1

Explanation of Output for Sample Input 2

When $B=102$, we can substitute into the formula and get $P=5\times 102-400$ which equals $110$. Since $110$ kPa is greater than $100$ kPa, you are below sea level.
