### Q. What is Regular Set in TOC ?

**Ans.**Regular sets are set which are accepted by FA (finite automata).

For example:

L = {ε, 11, 1111, 111111, 11111111…}

Here L is language set of even number of 1’s.

Finite automata for above language L is,

The give set L is regular set because we can represent it using finite automta.
