So far in the course, you've learned about a number of different problems you can run into when you have dirty data, including data type constraints, range constraints, uniqueness constraints, and membership constraints. It's important to be able to correctly identify the type of problem you're dealing with so that you can treat it correctly. In this exercise, you'll practice identifying these problems by mapping dirty data scenarios to their constraint type.
