Use the pumping lemma to show that the following languages are not regular.

A a. A1={0^n 1^n 2^n | n≥0}
b. A2 = {www | w ∈ {a,b}∗}

A c. A3 ={a^2^n | n≥0} (Here, a^2^n means a string of 2^n a’s.)

A ={a³ⁿ |n ^{> 0 }}

Use the pumping lemma to show that the following languages are not regular (c) (5 pts) Let Σ = {0, 1, −, =} and SUB = {x = y − z | x, y, z are binary integers, and x is the result of the subtraction of z from y}. For example: 1 = 1 − 0, 10 = 11 − 01 are strings in SUB but not 1 = 1 − 1 or 11 = 11 − 10.
