## LeetCode 509E - Fibonacci kth number ## 写法1 class Solution: def fib(self, n: int) -> int: if n in range(0,2): return n else: return fib(n-1) + fib(n-2) ## 这里递归函数对往后的元素全部引用了递归,所以叫完全递归;如果是部分元素使用,则称为“尾递归”。 ## 由于尾递归使...
13. 斐波那契数列(Fibonacci Number) 3 年前· 来自专栏 算法笔记 Alice it关注一. 题目: 今天的题目异常简单,考的是斐波那契数列,也就是后一个数字等于前两个数字之和。 看到要求是入参n小于30,这么小的数字,当然用数组解决最快,用递归太慢。 几分钟搞定。二. 我的代码...
[LeetCode] 509. Fibonacci Number 斐波那契数字 The Fibonacci numbers, commonly denotedF(n)form a sequence, called the Fibonacci sequence, such that each number is the sum of the two preceding ones, starting from0and1. That is, F(0) = 0, F(1) = 1 F(N) = F(N - 1) + F(N - ...
菲波那切数列(Fibonacci Number) 什么是菲波那切数列?自己google一下,面试题里面经常遇到,考试递归算法用的。 在菲波那切数列中用递归不太好。第三种算法最好。 第一 递归算法最差了,不想说。测试一下,当N=6000时,半天出不来数据,有想砸电脑的冲动。 第二 数组 在N变大后,空间浪费严重。 第三 队列 最好...
Codechef:Fibonacci Number/FN——求通项+二次剩余+bsgs 题意 定义$F_n$ 为 $$F_n = \left\{\begin{matrix} 0, n=0\\ 1, n=1 \\ F_{n-1} + F_{n-2}, n > 1 \end{matrix}\right.$$ 现给你一个素数 $p$ 和一个非负整数 $C$,你需要最小的非负整数 $n$,使得 $F_n \equiv...
