WORST_CASE(?,O(n^1))
* Step 1: Ara WORST_CASE(?,O(n^1))
    + Considered Problem:
        - Strict TRS:
            eq0(0(),0()) -> S(0())
            eq0(0(),S(x)) -> 0()
            eq0(S(x),0()) -> 0()
            eq0(S(x'),S(x)) -> eq0(x',x)
        - Signature:
            {eq0/2} / {0/0,S/1}
        - Obligation:
            innermost runtime complexity wrt. defined symbols {eq0} and constructors {0,S}
