Problème
Body mass index (BMI) is weight in kilograms divided by the square of height in meters.
Implement body_mass_index(weight_kg, height_m).
Input
weight_kg: Weight in kilograms. height_m: Height in meters.
Output
Return weight_kg / (height_m × height_m).
Contraintes
1 ≤ weight_kg ≤ 500; 0.5 ≤ height_m ≤ 2.5
Exemples
Exemple 1
Entrée :
height_m = 1.8
weight_kg = 72.0
Sortie attendue :
expected = 22.222222Entrée :
double height_m = 1.8;
double weight_kg = 72.0;
Sortie attendue :
double expected = 22.222222;Entrée :
double height_m = 1.8;
double weight_kg = 72.0;
Sortie attendue :
double expected = 22.222222;Explication
1.8 × 1.8 = 3.24 and 72 / 3.24 ≈ 22.2222.
Exemple 2
Entrée :
height_m = 1.0
weight_kg = 50.0
Sortie attendue :
expected = 50.0Entrée :
double height_m = 1.0;
double weight_kg = 50.0;
Sortie attendue :
double expected = 50.0;Entrée :
double height_m = 1.0;
double weight_kg = 50.0;
Sortie attendue :
double expected = 50.0;Explication
With a height of 1 meter the BMI equals the weight: 50.
