Question

A language consists of strings that have n copies of the letter a followed by the same number of copies of the letter b, where n > 0. Define the grammar specification for the language.

Answer 1

To define the grammar specification for the given language, we can use a context-free grammar.

Step-by-step explanation:

To define the grammar specification for the given language, we can use a context-free grammar. Let's denote the letter a as 'A' and the letter b as 'B'. The grammar specification can be represented as follows:

1. S --> AB
2. A --> aA | 'a'
3. B --> bB | 'b'

This grammar specification states that a valid string in the language consists of one or more 'a's followed by the same number of 'b's. It can be derived by starting with the non-terminal symbol S and repeatedly applying the production rules until only terminal symbols (a's and b's) are left.
