Consider the following language. L3={aibiajbji>j} When proving that L3 is not context-free by using the Pumping Lemma for context-free languages one must decide on a counterexample s. For each of the following, argue whether or not s is a successful choice to serve as counterexample. 1. s=a2pb2papbp 2. s=apbpa2pb2p 3. s=ap+1bp+1apbp
