* Step 1: Failure MAYBE
  + Considered Problem:
      - Strict TRS:
          a__diff(X,Y) -> a__if(a__leq(mark(X),mark(Y)),0(),s(diff(p(X),Y)))
          a__diff(X1,X2) -> diff(X1,X2)
          a__if(X1,X2,X3) -> if(X1,X2,X3)
          a__if(false(),X,Y) -> mark(Y)
          a__if(true(),X,Y) -> mark(X)
          a__leq(X1,X2) -> leq(X1,X2)
          a__leq(0(),Y) -> true()
          a__leq(s(X),0()) -> false()
          a__leq(s(X),s(Y)) -> a__leq(mark(X),mark(Y))
          a__p(X) -> p(X)
          a__p(0()) -> 0()
          a__p(s(X)) -> mark(X)
          mark(0()) -> 0()
          mark(diff(X1,X2)) -> a__diff(mark(X1),mark(X2))
          mark(false()) -> false()
          mark(if(X1,X2,X3)) -> a__if(mark(X1),X2,X3)
          mark(leq(X1,X2)) -> a__leq(mark(X1),mark(X2))
          mark(p(X)) -> a__p(mark(X))
          mark(s(X)) -> s(mark(X))
          mark(true()) -> true()
      - Signature:
          {a__diff/2,a__if/3,a__leq/2,a__p/1,mark/1} / {0/0,diff/2,false/0,if/3,leq/2,p/1,s/1,true/0}
      - Obligation:
          innermost runtime complexity wrt. defined symbols {a__diff,a__if,a__leq,a__p,mark} and constructors {0,diff
          ,false,if,leq,p,s,true}
