I am having trouble understanding this in C programming. I do not understand what it means when the "RHS" shows up before on the "LHS" and what exactly to do with the values in the case of the for loop for "i" starting the other way around. I understand how to do this method and have gotten the correct answer I just do not know what I would do if the situation "BEWARE" occurs. Please explain what I would have to change in this case.
