You are given two sequences of integer numbers. Write a program to determine their common increasing subsequence of maximal possible length. Sequence S1, S2, ..., SN of length N is called an increasing subsequence of a sequence A1, A2, ..., AM of len…

\(Greatest Common Increasing Subsequence\) 大致题意:给出两个长度不一定相等的数列,求其中最长的公共的且单调递增的子序列(需要具体方案) \(solution:\) 这道题如果不看具体方案,且我们要求的子序列不存在相同的元素,那么我们可以用 \(cdq\) 分治来搞搞,首先我们记录第二个数列中的元素在第一个数列里出现的位置(假设不存在重复,没有的不管),然后我们的第二个数列的每一个元素就有两个权值了,这是我们只需要两个权值均单调递增即可(这是 $cdq…

Sample Input 5 1 4 2 5 -12 4 -12 1 2 4 Sample Output 2 1 4 题目:给你两个数字序列,求出这两个序列的最长公共上升子序列.输出最长的长度,并打表输出.可能存在多种正确答案,故此题是special judge! 分析:dp[i][j] : A[1...i]和B[1...j]的公共上升子序列中以B[j]为结尾的最长的长度.如果A[i] != B[j], 则dp[i][j]=d[i-1][j]; 也就是说当前这个A[i]是没效用的.如果A[i]…
