def fib(self, n: int) -> int: if n < 2: return n return self.fib(n-1) + self.fib(n-2) 方法2:把f(n)每个值全存下来,直接调用 class Solution: def fib(self, n: int) -> int: f = [] f.append(0) f.append(1) if n < 2: return n for i in range(2,n+1): f.appen...
Consider the following code that computes the Fibonacci sequence of a series of numbers using a recursive algorithm. 🔴 Low-quality code: Python efficiency_v1.py from time import perf_counter def fibonacci_of(n): if n in {0, 1}: return n return fibonacci_of(n - 1) + fibonacci_of...
基础练习 Fibonacci数列 问题描述 Fibonacci数列的递推公式为:Fn=Fn-1+Fn-2,其中F1=F2=1。 当n比 较大时,Fn也非常大,现在我们想知道,Fn除以10007的余数是多少。 通过定义for循环,根据公式更新数列中的Fn,同时直接与10007取余进行计算;不需要算出具体数字再进行取余 因为如果<10007,取余后的数字还是原数,...

ref=appTake a look at this code for compute the fibonacci series. Regards kiuziu 3rd Nov 2019, 12:16 AM Kiuziu 💘 Berlin + 3 The computer is not lying. You've created a while loop which keeps looping while a < 21 but you don't change the value of a. If the code ever got...
