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 self.fib(n-1) + self....
I'm trying to solve a problem in python3. The thing is that I have to solve it on replit. When I run the code, it works, but when I run the tests, they don't pass and it appears Runtime error : input(): lost sys.stdin The problem is: Make the fibonacci sequence. The us...
