find the cube root of a number in rust

To find the cube root of a number in Rust, you can use the built-in cbrt function from the math module. Here's an example:

main.rs
use std::f64::cbrt;

fn main() {
    let num = 27.0;
    let cube_root = cbrt(num);
    println!("The cube root of {} is {}", num, cube_root);
}
145 chars
8 lines

This will output:

main.rs
The cube root of 27 is 3
25 chars
2 lines

Note that the cbrt function returns a f64 (double precision float) value, so you may want to round or truncate the result if you need an integer.
