[Question][Hw1] Expected Vigenere decryption is upper case #225

Name: Jeho Yeon

In README, it says that plaintext has to be lowercase.

For simplicity, we only consider messages written in the English alphabet. All the other characters will be ignored (e.g., numbers and whitespaces). Lowercase alphabet will be used to represent plaintext, while uppercase alphabet will be used to represent ciphertext.

But expected Vigenere decryption is uppercase.

Can I assume that decryption of vigenere has to be uppercase?

I found that it's duplicate of #222!
