What Does Mean The Language Is Closed? |
|
Answer» When we say that a LANGUAGE is CLOSED it is always with respect to certain operation. A simple example may be that the SET of INTEGERS is closed under addition. It means when we take two numbers from set of integers say 3, 7 the result of their addition would also be in the set of integers. Similarly if the result of an operation on the words of a language results in the word of the same language we say that the language is closed under that operation.
