deffib(n): memo = {0:0,1:1}foriinrange(2,n+1): memo[i] = memo[i-1] + memo[i-2]returnmemo[n] 解释 for循环的左边是因为备忘录里面已经有键0,1了,所以从2开始。然后我们最后要计算的是memo[n],i = n所以要为n+1 优化 这个的时间复杂度会大大降低,两者看似都是查表,但是由下而上...
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...
Recall thatPython Tutoris designed to imitate what an instructor in an introductory programming class draws on the blackboard: Thus, it is meant to illustrate small pieces of self-contained code that runs for not too many steps. After all, an instructor can't write hundreds of lines of code...

Hi, everyone. 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

写一个函数,输入n,求斐波那契(Fibonacci)数列的第n项(即F(N))。斐波那契数列的定义如下: F(0) = 0, F(1) = 1 F(N) = F(N - 1) + F(N - 2), 其中 N > 1. 斐波那契数列由0和1开始,之后的斐波那契数就是由之前的两数相加而得出。
