* Step 1: Failure MAYBE
  + Considered Problem:
      - Strict TRS:
          count(n,x) -> if(isEmpty(n)
                          ,isEmpty(left(n))
                          ,right(n)
                          ,node(left(left(n)),node(right(left(n)),right(n)))
                          ,x
                          ,inc(x))
          if(false(),false(),n,m,x,y) -> count(m,x)
          if(false(),true(),n,m,x,y) -> count(n,y)
          if(true(),b,n,m,x,y) -> x
          inc(0()) -> s(0())
          inc(s(x)) -> s(inc(x))
          isEmpty(empty()) -> true()
          isEmpty(node(l,r)) -> false()
          left(empty()) -> empty()
          left(node(l,r)) -> l
          nrOfNodes(n) -> count(n,0())
          right(empty()) -> empty()
          right(node(l,r)) -> r
      - Signature:
          {count/2,if/6,inc/1,isEmpty/1,left/1,nrOfNodes/1,right/1} / {0/0,empty/0,false/0,node/2,s/1,true/0}
      - Obligation:
          innermost runtime complexity wrt. defined symbols {count,if,inc,isEmpty,left,nrOfNodes
          ,right} and constructors {0,empty,false,node,s,true}
