Digits of a number fail
Now that you've written a successful test, write a test that will fail when it encounters unexpected behavior at an edge case.
Software engineers often intentionally write failing tests to demonstrate the existence of a bug.
The necessary JUnit packages have been imported for you.

@____
void testLastDigit() {
int number = -2025;
int expected = 5;
// Call the method under test
int actual = LastDigit.____(____);
// Use the correct JUnit assertion for the scenario
____(expected, actual);
