在学递归的时候,用递归实现了一个 下面是代码 def fib(n): if n >= 3: return fib(n-1)+fib(n-2) else: return 1 print(fib(6)) 发现一个很严重的问题:当数字比较小的时候还好,但是当求30以后的数字的时候,就会运行特别长的时间 所以请看下面一种方法 while True: def fib(n): result = [1,1] for i in range(n-2): result.append(result[-2]+resul

es5实现斐波拉契函数数列: <script type="text/javascript"> function fibonacci(n) { var one = 1; var two = 1; for(var i = 3; i <= n; i++) { //此处代码重点部分,用three累加前两个数的和,也是斐波那契数列的精髓所在. var three = one + two; one = two; two = three; } if (n==1||n==2) { /
1.斐波那契 什么是斐波那契,斐波那契额就是一个序列的整数的排序,其定义如下: Fn = Fn-1 + Fn-2 with F0 = 0 and F1 = 1 也就是,0,1,1,2,3,5,8,13..... 递归实现: def fib(n): if n == 0: return 0 elif n == 1: return 1 else: return fib(n-1) + fib(n-2) 非递归实现: def fibi(n): a, b = 0, 1 for i in range(n):
