comment What does O(n+k) mean verbally
@ThomasAndrews Do you mean that k or n drops out usually because of having less order rather than the other one? Or do you mean O(n+k) is e.g. O(n+5) and is different from O(n+m)?

comment What does O(n+k) mean verbally
I am considering k as a variable like n. Like some graph theory algorithms which run in O(m+n)

@did I think this post is supposed to be a HINT for OP not a formal proof.
