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_...
第一个是使用队列的方式: 1deffibonacciSeq(num):2fibonacciSeqList =[]3foriinxrange(0, num):4iflen(fibonacciSeqList) < 2:5fibonacciSeqList.append(1)6continue7fibonacciSeqList.append(fibonacciSeqList[-1]+fibonacciSeqList[-2])8fibonacciSeqList.pop(0)9returnfibonacciSeqList[-1] 第二个同样使用...
Python实现 importsys#循环 返回第 n 个数defloop(n):first,second=0,1foriinrange(n):first,second=second,first+secondreturnfirst#循环,返回斐波那契数列deffib(n):v=[0,1]foriinrange(2,n+1):v.append(v[i-1]+v[i-2])returnv# return v[n]if__name__=='__main__':print(fib(int(sys....
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...
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...

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...
Python3 实例斐波那契数列指的是这样一个数列 0, 1, 1, 2, 3, 5, 8, 13,特别指出:第0项是0,第1项是第一个1。从第三项开始,每一项都等于前两项之和。 Python 实现斐波那契数列代码如下:实例(Python 3.0+) # -*- coding: UTF-8 -*- # Filename : test.py # author by : www.runoob.com #...
Java for Loop Java while and do...while LoopDisplay Fibonacci Series The Fibonacci series is a series where the next term is the sum of the previous two terms. The first two terms of the Fibonacci sequence are 0 followed by 1. Fibonacci Series: 0, 1, 1, 2, 3, 5, 8, 13, 21, ...
