In this program, you are required to implement the Vigenère cipher algorithm from scratch, to encrypt and decrypt for alphabet string. The encrypt and decrypt method should be pure functions, i.e. without side effects.

The encoder and decoder circuits for the Vigenere cipher are therefore proposed in this work in QCADesigner by utilizing Peres and DG gates in quantum-dot cellular automata (QCA) that consist of a single layer with 42 cells for encryption and 47 cells for decryption. The proposed circuit ...

in which case you could try a different starting 'parent' and rerun the program. It may simply be that the ciphertext is too short, or contains too many rare quadgrams. This will mean garbled text may score higher than the original English. This is a limitation of any algorithm based on...
