4阶斐波那契序列如下：f0=f1=f2=0, f3=1,…,fi=fi-1+fi-2+fi-3+fi-4，

利用容量为k=4的循环队列，构造序列的前n+1项（f0, f1 , f2 ,… fn ），要求满足fn ≤200而fn+1 >200

-Fibonacci sequence of order 4 as follows: f0 = f1 = f2 = 0, f3 = 1, ..., fi = fi-1+ fi-2+ fi-3+ fi-4, with size k = 4 of the cycle for the queue constructed sequence of the first n+1 items (f0, f1, f2, ... fn), required to meet the fn ≤ 200 and fn+1>　200
