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_...
2. 循环迭代法 (效率更高) Python 1def fibonacci_iterative(n): 2 if n <= 0: 3 return [] 4 elif n == 1: 5 return [0] 6 elif n == 2: 7 return [0, 1] 8 else: 9 fib_sequence = [0, 1] 10 for _ in range(2, n): 11 fib_sequence.append(fib_sequence[-1] + fib_se...
### 方法一：使用循环 ```python def fibonacci_sequence(n):sequence = [0, 1]for i in range(...
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...

A coding kata -- Fibonacci sequence 斐波拉契数列(Fibonacci sequence),想必读者都已经非常熟悉了,指的是一个这样的数列: 0,1,1,2,3,5,8,13,21,34…… 这个数列从第3项开始,每一项都等于前两项之和。 伊始 如何用计算机解决这个问题,最简单的办法好像就是递归实现了,不知道读者是否考虑过下面几个小问题...

第4篇斐波那契数列python实现知识点:递归和循环要求大家都知道斐波那契数列,现在要求输入一个整数n,请你输出斐波那契数列的第n项。 n<=39斐波那契数列的定义: F(0)=0,F(1)=1, F(n)=F(n-1)+F(n-2)(n>=2,n∈N*)代码版本1:class Solution: def Fibonacci(self, n): # 定义: F ...
LeetCode 0509. Fibonacci Number斐波那契数【Easy】【Python】【动态规划】 Problem LeetCode TheFibonacci numbers, commonly denotedF(n)form a sequence, called theFibonacci sequence, such that each number is the sum of the two preceding ones, starting from0and1. That is, ...
Using Iteration and a Python Function The example in the previous sections implements a recursive solution that uses memoization as an optimization strategy. In this section, you’ll code a function that uses iteration. The code below implements an iterative version of your Fibonacci sequence algorith...
