WORST_CASE(?,O(n^1))
* Step 1: Ara WORST_CASE(?,O(n^1))
    + Considered Problem:
        - Strict TRS:
            add(0(),y) -> y
            add(s(x),y) -> s(add(x,y))
            main(x,y) -> add(x,y)
        - Signature:
            {add/2,main/2} / {0/0,s/1}
        - Obligation:
            innermost runtime complexity wrt. defined symbols {add,main} and constructors {0,s}
    + Applied Processor:
        Ara {minDegree = 1, maxDegree = 2, araTimeout = 5, araRuleShifting = Nothing}
