Mr. Hager is teaching Computer Science. It's currently the $N$-th day of the school year, and he created an assignment that's due on the $M$-th day of the school year.

Unfortunately, he noticed that his class gets stressed out very easily. If his assignment is due today or tomorrow, his students are stressed. If it's due later than that, his students are feeling okay. If the assignment's due date already passed, then it has been handed in and his students are feeling relaxed.

Mr. Hager wants to know how his students are feeling on a given day, as teachers should. You're a diligent Computer Science student, so he asks you to write a program to help him.
