简介: 在Python中实现斐波那契数列(Fibonacci sequence)的4中方法 1. 递归方法 (简洁但效率低,尤其对于较大的n值) Python 1def fibonacci_recursive(n): 2 if n <= 0: 3 return "输入的数值应大于0" 4 elif n == 1: 5 return 0 6 elif n == 2: 7 return 1 8 else: 9 return fibonacci_...
Python实现婓波那契数列(Fibonacci sequence) 一、斐波那契数列(Fibonacci sequence) 斐波那契数列(Fibonacci sequence)是一个非常神奇和有趣的数列,又被称为黄金分割数列或兔子数列。 在数学上,斐波那契数列定义为:第一项F(1)=0,第二项F(2)=1,而后续每一项都是前两项的和,即F(n)=F(n-1)+F(n-2)(n≥3)...
A Fibonacci sequence is the integer sequence of 0, 1, 1, 2, 3, 5, 8... The first two terms are 0 and 1. All other terms are obtained by adding the preceding two terms. This means to say the nth term is the sum of (n-1)th and (n-2)th term. Source Code # Program to ...
使用Python实现斐波那契数列(Fibonacci sequence) 斐波那契数列形如 1,1,2,3,5,8,13,等等。也就是说,下一个值是序列中前两个值之和。写一个函数,给定N,返回第N个斐波那契数字。例如,1返回1 6返回8 我选择了两种方法,一种是将list变成一个队列,另一个则是使用环形队列。不多说,直接上代码;后面我会对为什...

斐波那契数列(Fibonacci sequence),又称黄金分割数列、因意大利数学家列昂纳多·斐波那契(Leonardoda Fibonacci)以兔子繁殖为例子而引入,指的是这样一个数列:1、1、2、3、5、8、13、21、34。。。这个数列从第3项开始,每一项都等于前两项之和。 根据以上定义,用python定义一个函数,用于计算斐波那契数列中第n项的数字...
