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, F(0)=0,F(1)=1F(N)=...
解法一: fibonacci_list = [1, 1] while fibonacci_list[-2] + fibonacci_list[-1] <= 10 ** 9: fibonacci_list.append(fibonacci_list[-2] + fibonacci_list[-1]) class Solution: def findMinFibonacciNumbers(self, k: int) -> int: ans = 0 for num in fibonacci_list[::-1]: if k >=...
returnfibonacci(n - 1) + fibonacci(n-2) def test_10_v0(list_of_numbers): output = [] foriinnumbers: output.append(fibonacci(i)) returnoutput 然后我们使用Python的内置functools的lru_cache函数。 # Example of efficient code # Using Pytho...
斐波那契数列(Fibonacci sequence),又称黄金分割数列,指的是这样一个数列:0、1、1、2、3、5、8、13、21、34、…. 数学上的定义如下: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 n=0: F(0)=0 n=1: F(1)=1 n>=2: F(n)=F(n-1)+F(n-2) 代码实现 需要输出斐波那契数列的第 n 个...
