Increase your chance of getting help and look like a pro by sharing codeblocks not images. For example, you can type the following. Note, the ``` must be on their own line.
```
for number in range(10):
total += number;
```
Discord will render that as so:
for number in range(10):
total += number;

What is the error message?

Does that also show what command was run? What the input is?
If not, you can find it in the test file, line 93
sullen nacelle
hamming.sh 'AAA' 'A?A'

Also, please read the bot message and use codeblocks
What's your code output for those inputs? Do you understand why? What should it output? Do you understand why?
