Hint 1: In the code, the variable `element` represents an item from the Vec as it is being iterated.
|
In the first function we are looping over the Vector and getting a reference to one `element` at a time.
|
||||||
Can you try multiplying this?
|
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:

||||||
Hint 2: For the first function, there's a way to directly access the numbers stored
|
In the second function this dereferencing is not necessary, because the map function expects the new value to be returned.
|
||||||
in the Vec, using the * dereference operator. You can both access and write to the
|
|
||||||
number that way.
