Question 3: Caesar Cipher we write the message and then shift the alphabet by some specified number of letters. For example, he might choose to shift the alphabet by 4 letters. Then, A is replaced by E, B is replaced by F, and so on. When we reach V, it becomes Z. After that, we go back to the beginning so that W becomes an A, X becomes a B, and so on. One approach to breaking some encryption is brute force. If we know it was a Caesar cipher, then there are only 25 possible shifts, so we can just test them all until we find one that seems right. You are required to provide a code to decrypt the following message using Brut Force technique. "GUVF VF ZL FRPERG ZRFFNTR."

Question 3:
Caesar Cipher we write the message and then shift the alphabet by some specified number of letters. For example, he might choose to shift the alphabet by 4 letters. Then, A is replaced by E, B is replaced by F, and so on. When we reach V, it becomes Z. After that, we go back to the beginning so that W becomes an A, X becomes a B, and so on.
One approach to breaking some encryption is brute force. If we know it was a Caesar cipher, then there are only 25 possible shifts, so we can just test them all until we find one that seems right.
You are required to provide a code to decrypt the following message using Brut Force technique.
"GUVF VF ZL FRPERG ZRFFNTR."
