Remove Singleton

June 6, 2014

I’m not sure if this is a homework exercise or an interview questions, but it’s a fun little exercise to get your creative juices flowing on a Friday morning:

Given a string and a character, remove from the string all single occurrences of the character, while retaining all multiple consecutive instances of the character. For instance, given string “XabXXcdX”, removing singleton Xs leaves the string “abXXcd”.

Your task is to write the program given above; be sure to properly test your work. When you are finished, you are welcome to read or run a suggested solution, or to post your own solution or discuss the exercise in the comments below.
