Exercise: Geometry

We will create a few utility functions for 3-dimensional geometry, representing a point as [f64;3]. It is up to you to determine the function signatures.

// Calculate the magnitude of a vector by summing the squares of its coordinates
// and taking the square root. Use the `sqrt()` method to calculate the square
// root, like `v.sqrt()`.

{{#include exercise.rs:magnitude}}
fn magnitude(...) -> f64 {
    todo!()
}

// Normalize a vector by calculating its magnitude and dividing all of its
// coordinates by that magnitude.

{{#include exercise.rs:normalize}}
fn normalize(...) {
    todo!()
}

// Use the following `main` to test your work.
