arrays

Instructions

Define a function call thirtytwo_tens that returns an array with 32 positions fill with only the value 10: [10, 10, 10, ... 10].len() = 32

Write a function that takes an array of i32 and returns the sum of the elements (make it work with the main)

Expected functions

The type of one of the arguments is missing use the example main function to determine the correct type.

fn sum(a: _) -> i32 {
}

fn thirtytwo_tens() -> [i32; 32] {
}

Usage

Here is a program to test your function.

There is things missing in this program use the output and the other information that you have available to determine what is missing.

use arrays::{sum, thirtytwo_tens};

fn main() {
	let a = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
	let a1: Vec<i32> = (1..11).;
	let b = [_; 10];

	println!("The Sum of the elements in {:?} = {}", a, sum(a));
	println!("The Sum of the elements in {:?} = ", a1, sum(a1));
	println!("The Sum of the elements in {:?} = {}", b, sum(b));
	println!(
		"Array size {} with only 10's in it {:?}",
		thirtytwo_tens().len(),
		thirtytwo_tens()
	);
}

And its output
