WORST_CASE(?,O(n^1))
* Step 1: Bounds WORST_CASE(?,O(n^1))
    + Considered Problem:
        - Strict TRS:
            ++(x,nil()) -> x
            ++(++(x,y),z) -> ++(x,++(y,z))
            ++(.(x,y),z) -> .(x,++(y,z))
            ++(nil(),y) -> y
        - Signature:
            {++/2} / {./2,nil/0}
        - Obligation:
            innermost runtime complexity wrt. defined symbols {++} and constructors {.,nil}
    + Applied Processor:
        Bounds {initialAutomaton = minimal, enrichment = match}
    + Details:
        The problem is match-bounded by 1.
        The enriched problem is compatible with follwoing automaton.

    + Details:
        The problem is already closed. The intended complexity is O(1).
