Answer #1

Hi,

-------------------------------------

Followong is the PDA.

L4 13 LL L = {Q tambh | mzoanzoly & EG U {anong u U {fm amy o fanom among LI mi & nai nco mo m,mo z is bottom of stack b, b/

As provided L is divided into L1, L2, L3, L4.

L1 is accepted at q0.

L2 is accepted by q0 -> q1 -> q4.

L3 is accepted by the path q0 -> q2 -> q3

L4 is accepted by the path q0 -> q1 -> q2 -> q3 -> q4

q0, q3,q4 are final states

--------------------------------------------------------

Hope this helps

Please don't forget to give a thumbs up

Thanks
