Consider the language B = L (G), where G is the grammar given in Exercise 2.13 (page 121). The pumping lemma for context-free languages, Theorem 2.19 (page 115), states the existence of a pumping length p for B. What is the minimum value of p that works in the pumping lemma?

Recall that the minimum pumping length is the smallest positive integer l so that all words w of length at least l can be pumped with this pumping length, meaning that
w = uvxyz, |vy| > 0, |vxy| ≤ l , uvixyiz ? L for i = 0, 1, ...
The procedure is to start trying to pump the shortest words until we seem able
to pump everything, and then make the general ...
