Exercise 3.

Translate the following C-like piece of code into three-address code.
a = x * y + u * v - w * t; 
b = w * t - m * n;
while (b != 0) {
   tmp = a;
   a = b;
   while (tmp > b) {
      tmp = tmp - b;
   }
   b = tmp;
}
The three-address code instructions you may need are of one of the forms: Moreover your solution does not need to be obtained by one of the algorithms of the course. Just consider that you are programming a very basic calculator.
