Implement an encryption function that performs one round of encryption using S1 and S2 boxes with key generation schemes. Use binary plaintext (i.e. 100010110101 and key = 111000111) and print out the bit strings of L1R1, L2R2, L3R3, L4R4. Implement a decryption function that performs one round of decryption using the S1 and S2 boxes, and decrypts the L4R4 while printing out the bit strings of L3R3,L2R2,L1R1.
