I have 2 strings, with one being a substring of the other, like:
For the small string I have a label string:
What I would like to do is to first identify the "small" substring into the "big" one, and then add, respectively, 'I's and 'O's (or the opposite) in the start and end positions. I'm thinking to use index, would this be efficient solution? And how would I know how many 'O's and 'I's must I add in order for the "small" substring to grow into the length of the "big" one?
