Virtual Gate Test Series: Theory Of Computation - Regular and CFL Languages
Let $Σ = \{a, b, c\}$. Which of the following statements is true? For any $A ⊆ Σ^*$, if $A$ is regular, then so is $\{xx \mid x ∊ A\}$ For any $A ⊆ Σ^*$, if $A$ is regular, then so is $\{x \mid xx ∊ A\}$ ... so is $\{xx \mid x ∊ A\}$ For any $A ⊆ Σ^*$, if $A$ is context-free, then so is $\{x \mid xx ∊ A\}$
