假设银行整存整取存款不同期限的月息利率分别为：

0.63% 期限=1年

0.66% 期限=2年

0.69% 期限=3年

0.75% 期限=5年

0.84% 期限=8年

利息=本金*月息利率*12*存款年限。

现在某人手中有2000元钱，请通过计算选择一种存钱方案，使得钱存入银行20年后得到的利息最多(假定银行对超过存款期限的那一部分时间不付利息)。

*问题分析与算法

为了得到最多的利息，存入银行的钱应在到期时马上取出来，然后立刻将原来的本金和利息加起来再作为新的本金存入银行，这样不断地滚动直到满20年为止，由于存款的利率不同，所以不同的存款方法(年限)存20年得到的利息是不一样的。
