Very nice DP problem. The key fact of a mutual-divisible subset: if a new number n, is divisible with the largest number m within a mutual-divisible set s, s U {n} is also a mutal-divisible subset. class Solution { public: vector<int> largestDivisib…

最长递增子序列是动态规划中最经典的问题之一,我们从讨论这个问题开始,循序渐进的了解动态规划的相关知识要点. 在一个已知的序列 {a1, a 2,...an}中,取出若干数组成新的序列{ai1, ai 2,...aim},其中下标 i1.i2…im保持递增,即新数列中的各个数之间依旧保持原数列中的先后顺序,那么我们称新的序列{ai1, ai 2,...aim}为原序列的一个子序列.若在子序列中,当下标 ix > iy时,aix > aiy,那么我们称这个子序列为原序列的一个递增子序列.最长递增子…
