Each parking permit at a college has a unique identifier. The identifier must be made up of exactly three digits, followed by a forward slash, and then a single letter.
123/A, 045/x, and 981/Z are examples of valid permit identifiers.
Complete the table to show two additional validation tests and a piece of invalid data that would fail each test.
