And how would that be put in a decremental for loop? As I understand it, the loop starts at 2, performs its actions, and decreases by 1. I want it to stop at 0, so I put in the for loop for it to only decrement if it's greater than -1 (hence 2 and -1 as upper and lower bounds). This way, the only states that are accessed by the loop should be 2, 1, and 0.
