Hello, I need help solving these two computer science questions.
Homework Answers
3)
a)
GRAMMAR
S -> 0S1 | A | B
A -> 0A | 0
B -> 1B | 1
EXPLANATION
A is for 0+
B is for 1+
S is for equal number of 0's and 1's and to have extra 1's or extra
0s
b)
GRAMMAR
S -> 0S0 | 1A1
A -> 0A0 | 1B1
B -> 0B0 | 1C1
C -> 0C0 | epsilon
EXPLANATION
S is having 0 1's
A is having 1 1's
B is having 2 1's

For the remaining questions, consider a 4-bit block cipher, described in hexadecimal by the following table: Plaintext Ciphertext Plaintext Ciphertext 4 You can think of this as a simple substitution cipher for hexadecimal digits. The table itself serves as the "key" s (6 pts) For this question, you will perform encryption and 5. decryption using the same cipher described above, but in CBC mode. Recall that you can convert hexadecimal...

Give a CFG that generates the language L(a*b*c*) \ {
anbncn | n is a non-negative
integer }. This question is quite challenging; you will first need
to devise a good strategy for how the CFG should work and then
create the CFG to implement the strategy. You might want to do the
other questions first.
I'm so stuck on this question, can someone pls help me?
