I'm having troubles with implementing the wrap around method needed for passing this problem. As you will see, my code so far encypher a number of plaintext letters as equal as the number of the "key" elements prompted in the command line. I'm posting this because the walkthrough wasn't exhaustive for me to understand the problem. Hope to get some help https://gist.github.com/c7652d36e1356dec14d66ab2bab19638



I managed to solve it on my own.
