URL to the section(s) of the book with this problem:

https://github.com/rust-lang/book/blob/main/src/ch10-01-syntax.md

Description of the problem:

at the last example in section: In Function Definitions,

last example only suggests the reader to implement PartialOrd to compile the code but didn't show how. this is the code from book:

`fn largest<T>(list: &[T]) -> &T { let mut largest = &list[0];

for item in list {
    if item > largest {
        largest = item;
    }
}

largest

}

fn main() { let number_list = vec![34, 50, 25, 100, 65];

let result = largest(&number_list);
println!("The largest number is {}", result);

let char_list = vec!['y', 'm', 'a', 'q'];

let result = largest(&char_list);
println!("The largest char is {}", result);

}`

Suggested fix:

PartialOrd implemented version of the code above should be added to the book where it says implement partialord to make the prior code work.
