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.  If on…

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…

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.…

题目详情 如果序列 X_1, X_2, ..., X_n 满足下列条件,就说它是 斐波那契式 的: n >= 3 对于所有 i + 2 <= n,都有 X_i + X_{i+1} = X_{i+2} 给定一个严格递增的正整数数组形成序列,找到 A 中最长的斐波那契式的子序列的长度.如果一个不存在,返回  0 . (回想一下,子序列是从原序列 A 中派生出来的,它从 A 中删掉任意数量的元素(也可以不删),而不改变其余元素的顺序.例如, [3, 5, 8] 是 [3, 4, 5, 6, 7, 8…
