Question

Context Free Grammar

Step 1: Introduction

The below grammar expresses the concept of string concatenation, wherein the symbols "a" and "b" can be used to form strings from the alphabet set {a, b}. In addition to the string concatenation abilities, this grammar also establishes certain precedences and associativities among the symbols "a" and "b".
