GO Classes Test Series 2024 | Mock GATE | Test 11 | Question: 63
This question concerns two languages over the alphabet $\Sigma=\{1,-1\}$ (note that this is an alphabet with just two symbols: $1$ and $-1 ).$ The two symbols are interpreted, in the natural way, as the numbers $1$ and $-1,$ in ... $\text{L}_1$ Only $\text{L}_2$ Both None

Pumping Lemma
If there is a w’ such that w’ ∉ L in the final step of pumping lemma, then L is not regular (Lemma fails) Can we conversely say for certain if L is not regular, then definitely there is a w’ ∉ L. Simply : Can there be a case where we have all w’ ∈ L and still language is not regular?

#Regular Languages
For a particular input, a turing machine can ‘hang’ on encountering an infinite loop. Why can’t we say the same for any other machine? i.e A DFA or NFA that follows say a*(b). Will the automaton not ‘hang’ if a string $a^n$ where $n \to$ ∞ is fed to it? Isn’t ‘never accepting but progressing’ the same as hanging?

Checking regularity of a given language.
$L =\left \{ w(w^{R})^{*}: w\in(a,b)^{*} \right \}.$ Is this language regular?
