exercises/05_vecs/vecs1.rs: TODO clarification

[hikojlu]

exercises/05_vecs/vecs1.rs:

let a = [10, 20, 30, 40];
// TODO: Create a vector called `v` which contains the exact same elements as in the array `a`
// Use the vector macro

vec! macro can only be used like this: vec![10, 20, 30, 40].
Is it intended to be like this? I guess, it would make more sense to use Vec::from(a)

[frroossst]

I think what the exercise intended was vec![10, 20, 30, 40]

Although it wouldn't make much of a difference if you use Vec::from or the vec! macro
