MAYBE
* Step 1: Failure MAYBE
  + Considered Problem:
      - Strict TRS:
          append(cons(x,y),z) -> cons(x,append(y,z))
          append(nil(),y) -> y
          ge(x,0()) -> true()
          ge(0(),s(y)) -> false()
          ge(s(x),s(y)) -> ge(x,y)
          help(c,l,cons(x,y),z) -> if(append(y,cons(x,nil())),ge(c,l),cons(x,z),c,l)
          if(x,false(),z,c,l) -> help(s(c),l,x,z)
          if(x,true(),z,c,l) -> z
          length(cons(x,y)) -> s(length(y))
          length(nil()) -> 0()
          rev(x) -> if(x,eq(0(),length(x)),nil(),0(),length(x))
      - Signature:
          {append/2,ge/2,help/4,if/5,length/1,rev/1} / {0/0,cons/2,eq/2,false/0,nil/0,s/1,true/0}
      - Obligation:
          innermost runtime complexity wrt. defined symbols {append,ge,help,if,length,rev} and constructors {0,cons,eq
          ,false,nil,s,true}
