Summary about common substring Note points

This article describes a JavaScript custom function implementation method for finding the longest common substring of two strings. Share to everyone for your reference, specifically as follows://Find the longest common substring of two strings function Findsubstr (s1,s2) {var s=sstr= "", l1=s1.length,l2=s2.length; if (L1>L2) {var s3=s1;s1=s2,s2=s3,l1=s2.length;} for (var j=l1;j> 0; j--) for (Var i= 0&nbsp

2. LCS algorithm & maximum common substring & longest common subsequence PHP implements longest common ascending subsequence longest common subsequence C language longest public increment subsequence

Description: Longest common subsequence, Php:lcs algorithm & maximum common substring & longest common subsequence PHP implementation: Two maximum common substrings of a string & longest common subsequence input: ABCBDABBDCABA4, Bdcaba and Abcbdab The maximum common substring length is 4 general Idea enumeration method, calculates all the sub-sequences of two strings, and then compares each other to select the largest substring disadvantage: For a string of length n, the number of substrings has 2 N square, and then in order to compare the substring of two strings, the efficiency is too low dynamic planning The LCS algorithm uses the idea of dynamic programming to solve this problem, and we use a two-bit array of $
