Your tests are fine. But there might be one edge case you are missing out on. You handled 11 and 13; is there one more key group you might have missed?

There is a better arithmetic operator to be used for this function instead of string indexing. This ensures all edge cases are handled in your tests. To ensure code clarity and to avoid string manipulation
