Problem 35. Quote Doubler

This problem description would benefit from an example of the kind of input that could be expected (as well as the correct output).

Based on the description, I thought that I had to replace the string 'o'clock' with the string 'o''clock' (so making it usable in MATLAB.). And no, I did not manage to create input like that.

Instead, you want to replace every single quote with a double quote EXCEPT for the start-and-end quotes.
So 'o''clock' ==> 'o''''clock'

an example would make it clearer

I am not getting it .... Its always showing wrong

so weird!!!

I've found no matter how many '''' I add, it will only show one additional.
