Let = { a , b } . Consider the following regular grammars over . 5 + ( 4 * * 1 ) + 3

Let ={a,b}. Consider the following regular grammars over .5+(4**1)+3+4+4=20
L={w=w1w2cdotswn|(w1=wn??|w|-=0(mod2))vv(w1wn??|w|-=1(mod2)),n>0}
1
Ls={w=w1w2cdotswn|w1=wn,n>0}
Ld={w=w1w2cdotswn|w1wnn>0}
Le={w=w1w2cdotswn||w|0(mod2),n>0}
Lo={w=w1w2cdotswn||w|1(mod2),n>0}
(a) Design a DFA M for L.
(b) Design DFAs Ms,Md,Me,Mo for Ls,Ld,Le,Lo respectively.
(c) Express L in terms of Ls,Ld,Le,Lo.
(d) Using the relationship in Q (3c), connect the DFAs from Q (3b) to get an NFA N for L.
(e) Prove that L(M)=L(N)=L.
