P5714 [deep foundation 3. Case 7] obesity

BMI The index is a standard commonly used internationally to measure the degree of obesity and thinness of the human body , The algorithm is m/h^2
(40≤m≤120,1.4≤h≤2.0), among mm It refers to weight （ kg ）,hh Refers to height （ rice ）. The range and judgment results of different body types are as follows ：

Less than 18.5： Underweight , Output Underweight;
Greater than or equal to 18.5 And less than 24： Normal weight , Output Normal;
Greater than or equal to 24： obesity , Not only output BMI value （ Use cout The default precision of ）, And then line break , And output Overweight;
Now give weight and height data , Need basis BMI The index judges the shape state and outputs the corresponding judgment .

For non C++ Language , At output time , Please round Retain six significant digital outputs , If there is a suffix in the decimal part 00, Do not output suffixes 00.

Please note that , Keeping six significant digits is not keeping six decimal places . for example 114.5149114.5149 The output should be 114.515114.515,9198.109198.10 The output should be 9198.19198.1.

Input format
All in one line .

first line , common 22 A floating point number ,m,nm,n, Weight respectively （ Unit is kgkg）, height （ Unit is mm）.

Output format
nothing
