I successfully completed the Vigenere program and I was recently testing it with Check50. My problem is that there is only one test that fails, and I don't know why:
:( encrypts "BaRFoo" as "CaQGon" using "BaZ" as keyword \ expected output, but not "CaQGoh\n"
Here is my sandbox link: https://sandbox.cs50.net/checks/58eb0850663548a7bcd378320a860169.
What's going on behind the scenes?
