ISI 2013 Subjective
Q C4 b) If it is known that the language L1=$\left \{ 0^{n}1^{n}2^{i}\mid n\neq i \right \}$ is not a context free language (CFL). Now consider the language L2=$\left \{ 0^{i}1^{n}2^{n}\mid i\neq n \right \}$. We ... that L2 is not CFL by converting L2 into L1 by applying two operation, both know to be closed on CFLs. What are two operation you will use for this construction.

Professor Hijibiji has defined the following Boolean algebra $\mathcal{B} = (B, +, *)$, where $B = \{1, 2, 3, 5, 6, 10, 15, 30\}$, i.e., the set of all eight factors of $30$; the two binary operators $'+'$ and $'*'$ respectively denote the LCM ... common divisor) of two integer operands. Define the complementation operation $\bar{a}$ for all $a \in B$ such that $\bar{\bar{a}}= a$.
