Character counting string

You are given a string s. Your task is to count the number of characters in the string and return the total amount of characters in the string with the type u32.

Example

let s = "hello";
let result = character_counting_string(s);
assert_eq!(result, 5);

Hints

You can use the chars() method to get an iterator over the characters in the string.
You can use the count() method to count the number of elements in the iterator.

The count() method returns a usize which is the number of elements in the iterator. In the challenge you are asked to return a u32, you can use the as keyword to convert the usize to a u32. For example, let count_u32 = count as u32;
