Leetcode 509: 斐波那契数列(Fibonacci number) Python 招舟 来自专栏 · 量化交易 在数学上,斐波那契数是以递归的方法来定义:方法1:递归法,缺点是效率较低,因为每次都需要一次一次计算n之前的值 class Solution: def fib(self, n: int) -> int: if n < 2: return n return sel
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)=...
