Haskell - Body mass index P87082

Statement

html

The body mass index (BMI) is an attempt to quantify the amount of tissue mass (muscle, fat, and bone) in an individual, and then categorize that person as underweight, normal weight, overweight, or obese based on that value.

The BMI was conceived by Adolphe Quételet between 1830 and 1850 its formula is

BMI =
 m h2
,

where m is the mass of an individual (in kilograms) ans h is its height (en meters).

Its interpretation (only for adults) is the following:

 BMI Interpretation less than 18 underweight from 18 to 25 normal weight from 25 to 30 overweight from 30 to 40 obese more than 40 severely obese

Write a Haskell program to interpret the body mass index of several individuals.

Input

Input is organized in lines. Each line has three elements separated with whitespaces: the name, the weight and the height. The last line is special and only contains an asterisc.

Output

For each individual, print his/her name and the interpretation of his/her BMI.

Observation

In order to solve this problem in Haskell, write a main action and choose the GHC compiler.
