Question:
Prove the following generalization of the pumping lemma, which can sometimes make it unnecessary to break the proof into cases. If L can be accepted by an FA, then there is an integer n such that for any x ∈ L, and any way of writing x as x = x1x2x3 with |x2|=n, there are strings u, v, and w such that
a. x2 = uvw
b. |v| > 0
c. For every m ≥ 0, x1uvmwx3 ∈ L.
