Desafio de Programação Body Mass Index

Problema

Body mass index (BMI) is weight in kilograms divided by the square of height in meters.

Implement body_mass_index(weight_kg, height_m).

weight_kg: Weight in kilograms. height_m: Height in meters.

Return weight_kg / (height_m × height_m).

1 ≤ weight_kg ≤ 500; 0.5 ≤ height_m ≤ 2.5

Exemplo 1

Entrada:
height_m = 1.8
weight_kg = 72.0

Saída esperada:
expected = 22.222222

Entrada:
double height_m = 1.8;
double weight_kg = 72.0;

Saída esperada:
double expected = 22.222222;

Entrada:
double height_m = 1.8;
double weight_kg = 72.0;

Saída esperada:
double expected = 22.222222;

1.8 × 1.8 = 3.24 and 72 / 3.24 ≈ 22.2222.

Exemplo 2

Entrada:
height_m = 1.0
weight_kg = 50.0

Saída esperada:
expected = 50.0

Entrada:
double height_m = 1.0;
double weight_kg = 50.0;

Saída esperada:
double expected = 50.0;

Entrada:
double height_m = 1.0;
double weight_kg = 50.0;

Saída esperada:
double expected = 50.0;

With a height of 1 meter the BMI equals the weight: 50.
