PROGRAMMING:C programming experiment 2-3-2

Body shape judgment.
After extensive investigation and statistical analysis, according to the factors of height and weight, medical workers give the following methods to judge body shape according to body index
Body index t = weight W / (height h) $$^ {2} $$(unit: kg, H unit: m)
When T < 18, it was low weight;
When t is between 18 and 25, it is normal weight;
When t is between 25 and 27, it is overweight;
When t ≥ 27, it is obesity.
Enter your height h and weight W (both stored in real variables) from the keyboard, calculate the body index t according to the given formula, and then judge what type of weight you belong to.
###Input format:
Height and weight are given in a row, separated by spaces.
###Output format:
Output body index (two decimal places) and body weight type in one line, and leave two spaces between body index and body weight type.
###Input example:
```in
1.64 45

###Output example:
```out
16.73 Lower weight!
