求两个串的最大LCSLCS。 思路: 把第一个串建后缀自动机,第二个串跑后缀自动机,如果一个节点失配了,那么往父节点跑,期间更新答案即可。 代码: #include<set> #include #include<cmath> #include<queue> #include<bitset> #include<string> #include<cstdio> #include<vector> #include<cstring> #include <...
2. sol 1 longest common substring问题 3. dp每增加一个字母,最长列长度只可能增加1or2(思路:以当前字母为尾的最长列): class Solution: def longestPalindrome(self, s: str) -> str: if not s: return '' l = 1 start = 0 for i in range(2, len(s)+1): if i>l+1: if s[i-l-2:i...
1.对于数组的长度为0的时候返回的值未注意。 2.在循环比较序列是否连续的时候,没有想到可能存在两个数相等的情况,此时,对于序列长度的计数不能清零。
LCS(longest common substring)算法,即最大公共子串,它是求两个字符串最长公共子串的问题。大体解法是用一个矩阵来记录两个字符串中所有位置的两个字符之间的匹配情况,若是匹配则为1,否则为0。然后求出对角线最长的1序列,其对应的位置就是最长匹配子串的位置....
Given two strings, find the longest common substring. Return the length of it. Example Given A = "ABCD", B = "CBCE", return 2. 答案 public class Solution { /** * @param A: A string * @param B: A string * @return: the length of the longest common substring. */ /* f[i][...
