题目: The twenty-first century is a biology-technology developing century. We know that a gene is made of DNA. The nucleotide bases from which DNA is built are A(adenine), C(cytosine), G(guanine), and T(thymine). Finding the longest common subsequence…

题意:给定一些DNA序列,求一个最短序列能够包含所有序列. 思路:记录第i个序列已经被匹配的长度p[i],以及第i序列的原始长度len[i].则有两个剪枝: 剪枝1:直接取最长待匹配长度.1900ms int h = 0; for(int i = 0; i < n; ++i) { h = max(len[i] - p[i], h); //最大待匹配长度 } 剪枝二:统计每个序列里面四种序列值,并求得每种序列值的最长长度.将四种序列值加起来就是最长待匹配长度.180ms int cal() { /…

DNA sequence 直接中文了 题目描述 21世纪是生物科技飞速发展的时代.我们都知道基因是由DNA组成的,而DNA的基本组成单位是A,C,G,T.在现代生物分子计算中,如何找到DNA之间的最长公共子序列是一个基础性问题. 但是我们的问题不是那么简单:现在我们给定了数个DNA序列,请你构造出一个最短的DNA序列,使得所有我们给定的DNA序列都是它的子序列. 例如,给定"ACGT","ATGC","CGTT","CAGT"…

DNA Sequence 题意:DNA的序列由ACTG四个字母组成,如今给定m个不可行的序列.问随机构成的长度为n的序列中.有多少种序列是可行的(仅仅要包括一个不可行序列便不可行).个数非常大.对100000取模. 思路:推荐一个博客,讲的很清楚. 这样的题目.n非常大,首先想到的就是用矩阵来优化.那么怎样构造转移方程呢:首先建立一棵Trie,然后依照AC自己主动机的方式构造fail指针,然后会发现.当一个状态分别加入ACTG之后,会得到还有一个状态. (详细解释见代码) 代码: /* ID:…
