Writing code helped me understand the problem better

because I could actually test what was happening instead of just guessing.
It made it easier to see how encryption and decryption work step by step,
and I could quickly fix mistakes when something didn’t work.

I had trouble finding the secret word at first because I was only getting
numbers when I calculated the shifts. I couldn’t turn that into a readable word,
so I used the secret word provided by the professor instead. Then I used
 that word in PolyCipher to decrypt the message and check that it worked.
