Regular grammars are often used to represent regular languages, which are a class of languages that can be recognized by deterministic finite Automata DFAs or regular expressions. We want to generate strings that have a mistake or mismatch in the middle, causing them to be non-palindromic. By applying these rules recursively, we can generate palindromes of any length composed of 0 s and 1 s.
