Prove that the following language L is not a Context Free Language using the Pumping Theorem
D = { 0, 1, 2, 3, 5}
V = { a, e, i, o, u}
C = { d, f, g, h, j }
? = D ? V ? C
L = { w : amount(D) <
amount(V) < amount(C) }
"Amount of symbols in w that are elements of
D" < "Amount of symbols in w
that are elements of V" < "Amount of symbols in
w that are elements of C"
Express w in terms of the symbols in
?, not in terms of the D,
V, and C subsets
