I am not sure what I'm supposed to do in division 3-4 is there any stack command that detects that the top of the stack is negative? or something like that?
So I just checked the code, turns out the answer check for that task was looking for a program that puts the result, not the remainder in reg1.
I must have changed it and forgotten to update the task to match.
I just released an update changing 3-4's wording to match this. (release_v1.2.1)
Sorry about that.
