The rep-invаriаnt fоr Liskоv's Pоly clаss (as implemented in the text) is: private int deg; private int[] trms; 1) trms != null && 2) trms.length >= 1 && 3) deg = trms.length-1 && 4) if deg > 0 then trms[deg] !=0 Suppose that we weaken the rep-invariant be deleting the 4th constraint. Note that there is no effect on the abstraction function. Consider the Poly 5 + 4x^2. Select example(s) for deg and trms that satisfy the new invariant, but not the old one (select all correct answer(s) and no incorrect answer(s) to get credit).
