In the first function we are looping over the Vector and getting a reference to
one `element` at a time.
In the first function, we create an empty vector and want to push new elements
to it.
To modify the value of that `element` we need to use the `*` dereference
operator. You can learn more in this chapter of the Rust book:
https://doc.rust-lang.org/stable/book/ch08-01-vectors.html#iterating-over-the-values-in-a-vector
In the second function this dereferencing is not necessary, because the `map`
function expects the new value to be returned.
In the second function, we map the values of the input and collect them into a vector.
After you've completed both functions, decide for yourself which approach you
like better.
