5. Let = {0,1} and define a language L over E as L = {0" 10" 10" : n 21} Show that L is not context-free. Hint: Let p be the pumping constant and consider the string s = OP 10P 10'. Write s as in the Pumping Lemma. Either vy has no zeros, or it has at least one zero; consider these cases separately. 5.
