Body mass index is weight / height**2 with weight in kilograms and height in metres. Write bmi_category(weight_kg, height_m) that returns:
"underweight"if BMI is below 18.5"normal"if BMI is at least 18.5 and below 25"overweight"if BMI is at least 25 and below 30"obese"if BMI is 30 or more
Examples
Input: weight_kg = 70, height_m = 1.75
Output: "normal"
Input: weight_kg = 50, height_m = 1.8
Output: "underweight"
Input: weight_kg = 95, height_m = 1.7
Output: "obese"
Constraints
20 <= weight_kg <= 3001.0 <= height_m <= 2.5
Goals
- Compute a value and then classify it
- Use strict and non-strict comparisons correctly at the boundaries
