Use the pumping lemma to show that the following set is NOT regular:
{ww | w => {a,b}*}
Expert Answer
Pumping Lemma:
We can prove this by using pumping lemma which states that L is a regular language if there exists a constant n such that every string in w ∈ L, where |w| ≥ n, also there are strings x,y,z such that w = xyz and it must follow the following properties:
- |y|>=1,
- |xy| ≤ n,
- xykz ∈ L for all k ∈ N
The strings that we can get will be like first half will be equal to the second...
