We are currently using High level Assembly.
And our instructors gave us an exercise to find using only addition and subtraction command,i.e. add() and sub(); the problem is to find the positive difference between two numbers without using any control structures like if() and loops; only addition and subtraction that is..
I know this is only trivial but if there already availabel ideas, then why not use them...?
Hope you could help..

The point of this task is for you to learn to solve programming-oriented problems. Now how, exactly, are you supposed to learn this if we do your work for you?

Think a little. Prove you've done some work. Then come back and we'd be more than happy to help.

I've done all possible combination of addition and subtraction but to no avail.
Well if this is trivial if control structures are allowed..Already thought, but all I got is negative to positive, then positive to negative.
We are not even allowed to manipulate the bit representation of the numbers to be manipulated..well I think youre right, I am just being idle on my part..I'll think again..

Are you trying to find the absolute of a sum or subtraction?
