WebThe grammar for Pal is know to be the following: S -> lambda a b aSa bSb. The grammar for {a, b}* can be written as follows: S -> lambda Sa Sb. Now to construct the grammar of non-Pal observe the following: If x is an element of non-Pal then: axa is an element of non-Pal. bxb is an element of non-Pal.
