At sea level, atmospheric pressure is kPa and water begins to boil at . 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

where is atmospheric pressure measured in kPa, and is the temperature at which water begins to boil measured in .

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 and 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 where and . This represents the temperature in 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 , we can substitute into the formula and get which equals . Since kPa is less than 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 , we can substitute into the formula and get which equals . Since kPa is greater than kPa, you are below sea level.

This totally science and I USED to like science.

I hated this so much because I didn't read the text and what it said:

"The second line must contain the integer -1, 0, or 1."

REMEMBER TO PUT THE 0!!!

I was confused and then I read your comment and I solved this. Thanks a lot.
