On The Liniar Time Complexity of Finite Languages
  The present paper presents and proves a proposition concerning the time complexity of finite languages. It is shown herein, that for any finite language (a language for which the set of words composing it is finite) there is a Turing machine that computes the language in such a way that for any input of length k the machine stops in, at most, k + 1 steps.
