This challenge gives vendors of different rules-based tools an opportunity to demonstrate how they handle business rules with regular expressions. They need to implement business rules such as below:

• If the Degree Code is “MA Single” and the Course Code is similar to MA52# or MA62#, where # stands for any single character, add this course to the list of allowed courses.
• If the Degree Code is not “CS%” and the Course Code is similar to CS%288% or CS%289%, where % stands for any combination of characters, add this course to the list of not allowed courses. Link
