英文版A sequence X_1, X_2, ..., X_n is fibonacci-like if: - n >= 3- X_i + X_{i+1} = X_{i+2} for all i + 2 <= n Given a strictly increasing array A of positive integers forming a sequence, find the length of the longest fibonacci-like subsequence of A.
Given a string S of digits, such as S = "123456579", we can split it into a Fibonacci-like sequence [123, 456, 579]. Formally, a Fibonacci-like sequence is a list F of non-negative integers such that: 0 <= F[i] <= 2^31 - 1, (that is, each
斐波那契数列:1, 1, 2, 3, 5, 8, 13,...,即 f(n) = f(n-1) + f(n-2). 求第n个数的值. 方法一:迭代 public static int iterativeFibonacci(int n) { //简单迭代 int a = 1, b = 1; for(int i = 2; i < n; i ++) { int tmp = a + b; a = b; b = tmp; } return b; } 方法二:简单递归 public static long
今天遇到一个面试题:输入n,如果n<=1,f(n)=1,其他f(n)=f(n-1)+f(n-2), 打印f(n)从1到n的值. public class Fibonacci { private int n; private StringBuilder sb; private String format; @Before public void init() { n = 10; sb = new StringBuilder(n); format = "f(%s) = "; } 直接
