Deterministic Finite Automata (DFA) has several real-life applications. It is a useful tool in diversified areas like pattern matching, pattern recognition, control theory, text editors, lexical analyzer, and models of software interfaces. Several methods are developed to construct a DFA using Regular Expression (RE), set of strings, derivations in RE and regular grammar. The motivation for this paper is the observation that students find DFA construction as a tedious task in the early stage of learning. This paper provides a simple solution to the standard computation-theory problem that asks a student to construct a DFA for given language description (i.e., validation rules). The presented paper keeps the concerns of beginner level students at the core.
