Instructions
Complete the signature and the body of the str_len

}
Notions
Usage
Here is a possible program to test your function :
fn main() {
let s = "hello";
let s1 = "camelCase".to_string();
println!("\tstr_len(\"{}\") = {}", s, str_len(s));
println!("\tstr_len(\"{}\") = {}", s1, str_len(&s1));
}
And its output:
student@ubuntu:~/[[ROOT]]/test$ cargo run
str_len("hello") = 5
str_len("camelCase") = 9
student@ubuntu:~/[[ROOT]]/test$
