It is straightforward to show a counterexample: you insert three elements and perform one deleteOdds. The actual costs would be 2 + 2 + 2 + 3 = 9, while you only give a sum of 2 + 2 + 2 + 2 = 8 amortized costs. 4) If you write down accounting method but then you perform other methods following your “accounting method: ” notation, for example, you write immediately that “the sum of all actual costs is …”, or “define a potential function as …”, etc, then you will be deducted by 1 point from what your other method deserves to earn. 5) If you indeed use the accounting method, but only show that P(n) >=...
