समस्या
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).
सीमाएँ
1 ≤ weight_kg ≤ 500; 0.5 ≤ height_m ≤ 2.5
उदाहरण
उदाहरण 1
इनपुट:
height_m = 1.8
weight_kg = 72.0
अपेक्षित आउटपुट:
expected = 22.222222इनपुट:
double height_m = 1.8;
double weight_kg = 72.0;
अपेक्षित आउटपुट:
double expected = 22.222222;इनपुट:
double height_m = 1.8;
double weight_kg = 72.0;
अपेक्षित आउटपुट:
double expected = 22.222222;व्याख्या
1.8 × 1.8 = 3.24 and 72 / 3.24 ≈ 22.2222.
उदाहरण 2
इनपुट:
height_m = 1.0
weight_kg = 50.0
अपेक्षित आउटपुट:
expected = 50.0इनपुट:
double height_m = 1.0;
double weight_kg = 50.0;
अपेक्षित आउटपुट:
double expected = 50.0;इनपुट:
double height_m = 1.0;
double weight_kg = 50.0;
अपेक्षित आउटपुट:
double expected = 50.0;व्याख्या
With a height of 1 meter the BMI equals the weight: 50.
