举个例子,假如有两个字符串:ABCD 和ABDBCDF 他们的公共子串分别有:A, B, C, D, AB, BC, CD, BCD 其中最长的就是BCD了,所以BCD就是它们两个的最长公共子串,注意最长公共子串可能不止一个哦… 接下来先讲一种很简单很好理解的方法: 用例子来说明一切,还是上面的ABCD 和ABDBCDF 这两个字符串的长度分...
给定2个字符串$str1, $str2, 返回2个字符串的最长公共子串 e.g. $str1 = "1AB2345CD"; $str2 = "12345EF" 返回: "2345" 要求: 如果$str1 长度为M, $str2长度为N, 实现时间复杂度为O(MxN), 额外空间复杂度为O(1)的方法 * LCST.php AI检测代码解析 <?php /** * Created by PhpStorm....

For the two input sequences, X and Y , of lengths n andmand a constraint string, P, of length r, the goal is to find the longest common subsequence, Z, of X and Y that excludes P as a substring. The problem and its solution were first proposed by Chen and Chao, but we found ...
