$13.$ Add Test Cases for after$\_$space

When designing test cases for after$\_$space, think about how spaces may occur in the string $$ both position and frequency $$ and how that can effect the result. Because after$\_$space processes spaces differently than before$\_$space, there are certain tests that are important for after$\_$space that were not necessarily important for before$\_$space $($and vice versa$).$
