Convert the following grammar into Chomsky Normal Form
(CNF):
S → aS | A
| bS
A → aA |
bBa | aAa
B → bb |
bBb
Note: you need to first simplify the grammar ( remove any
λ -
productions, unit productions, and useless productions), and then
convert the simplified grammar to CNF.

How to prove that the grammar G is not LL(1) The grammar is: L => LE | E E => (C) | (F) | V | T C => ifEE | ifEEE F => +L | -L | *L | printL V => a | b | c | d T => 0 | 1 | 2 | 3
1. Factorize and the irreducible quadratic factors if there are any. as much as possible the following expressions, identify then the linear factors (a) -9 C)-3) (b) 3r2+ 5r-3 (e) (+7x-4)(-2r+2+) 2. By looking for evident roots in the range (-2,-1,0, 1,2} factorize as much as possible the following expressions. Finally, as in 1. identify linear and irreducible quadratic factors if there are any (a) -3r+2 (b) 2r +22 + }x (e) -2r+5-5r2+3r-1
