Problem 1049 - 斐波那契数 Time Limit: 1000MS Memory Limit: 65536KB Difficulty: Total Submit: 1673 Accepted: 392 Special Judge: No Description 斐波那契数列是如下的一个数列,0,1,1,2,3,5……,其通项公式为F(n)=F(n-1)+F(n-2),(n>=2) ,其中F(0)=0,F(1)=1,你的任务很简单,判定斐波契数列的第K项是否为偶数,如果是输…
Pandigital Fibonacci ends The Fibonacci sequence is defined by the recurrence relation: F[n] = F[n-1] + F[n-2], where F[1] = 1 and F[2] = 1. It turns out that F541, which contains 113 digits, is the first Fibonacci number for which the last nine digi…
The Fibonacci numbers, commonly denoted F(n) form a sequence, called the Fibonacci sequence, such that each number is the sum of the two preceding ones, starting from 0and 1. That is, F(0) = 0, F(1) = 1 F(N) = F(N - 1) + F(N - 2), for N > 1. Given …
本篇文章解决的问题来源于算法设计与分析课程的课堂作业,主要是运用多种方法来计算斐波那契数.具体问题及解法如下: 一.问题1: 问题描述:利用迭代算法寻找不超过编程环境能够支持的最大整数的斐波那契数是第几个斐波那契数.(Java: 231-1 for int, 263-1 for long) 解决方案:针对问题1,此处要使用迭代法来解决,具体实现代码如下: //用迭代法寻找编程环境支持的最大整数(int型)的斐波那契数是第几个斐波那契数 public static int max_int_iter…
