How to multiply characters in string by number after character?

It’s limitation is that the repetition factor has to be a single digit, e.g. 2 – 9. If we want repetition factors greater than 9, we have to do slightly more parsing of the string: Assuming that the format is always a letter followed by an integer, with the last integer possibly missing:
