Based on the Block Cipher answer the following $2$ questions:

a$.$ What is the encryption value of c$1$ and c$2$ i$.$e$.,$ what is the bitstring c$1$ and c$2$ produced by this CTR modes of encryption? Explain how you found values c$1$ and c$2$ as well

b$.$ With respect to the adversarial attack power, what is the highest possible adversarial attacking power that this encryption scheme will be able to withstand$F_2()$ is a secure block cipher.
