write a simple program in Java to implement the below approach for encryption and decryption (show sample output)

The computation of fi(x) in the ith round is (2i7)^x mod 15

the plaintext is 00101000

the ciphertext is 00111111

write a simple program in Java to implement the below approach for

Lo=0010 Ro=1000 F1=0001 L1=1000 R1=0011 F2=0111 L2=0011 R2=1111 Lo=0010 Ro=1000 F1=0001 L1=1000 R1=0011 F2=0111 L2=0011 R2=1111
