8. Find context-free grammars for the following languages (with n > 0, m 0,k 20).
(a) L = {a"6"c" : n= m or m sk}. S
(b) L = {abc: n = m or m #k}.
(c) L = {a”bmck: k = n + m}.
(d) L = {a”ymck: n + 2m = k}.
(e) L = {a”b”ck : k = In – ml}.
(f) L = {we {a, b,c}* : na (w) + no (w) # nc (w)}.
(g) L = {a"6ch, k +n+m}.
(h) L = {a"b" : k > 3}.
