A string is finite sequence of characters over a non-empty finite set Σ. In this problem, Σ is the set of lowercase letters. Substring, also called factor, is a consecutive sequence of characters occurrences at least once in a string. Now your task i…

LCS2 - Longest Common Substring II 多个字符串找最长公共子串 以其中一个串建\(SAM\),然后用其他串一个个去匹配,每次的匹配方式和两个串找\(LCS\)一样,就是要记录\(SAM\)的每个状态和当前匹配串匹配的最大值\(maxx\),这个在匹配完一个串之后需要通过\(parent\)树上传最大匹配值,同时要更新一个最小值\(minn\),来表示每个节点和当前已经匹配过的所有串能匹配上的最大值,这个需要每次匹配一个串之后和当前节点的\(maxx\)取\(min…
