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…
题意是求所给的数能够被拆分成的不同组合数目. 方法有三种: 一.完全背包. 限制条件:所用数字不大于 n. 目标:求分解种数(组合出 n 的方法数). 令 dp[ i ][ j ] = x 表示 用前 i 种数字组合出数字 j 有 x 种方法. 状态转移方程:dp[ i ][ j ] = dp[ i -1 ][ j ] + dp[ i ][ j - num[i] ] 方程解释:前 i 种数字组合出数字 j 的方法数 = 前 i - 1 种数字组合出数字 j 的方法数(不用第 i 种数字)+ 至少…
