Give a meaningful loop invariant relating the current values of , r , s, x, and y. (Hint: Look at the GCD loop invariant.) In addition to this invariant being true every time the computation is at the top of the loop, it will also be true every time the computation is between the first and the second step of each iteration. Prove that your algorithm establishes and maintains the loop invariant as stated.
