If it does not exist, then the short substring is reduced in length to take the substring, to d

) minus the position of the old A (cis-i-1), so the equivalent of j-i +1 = 4.When j = 5 o'clock, it is found that the map has a at this point J, so update the value of I, indicating that the previous a in the 5th, so ans_temp = 5-5+1 = 1, take max, ans eventually equals 4.Why not just save the label?If the storage is subscript, then the last update of ANS can only be j-i (new position minus the old position), if the entire string is not duplicated, then the final answer is length-1-0, because on

1 The topic is to give two strings, and then to find the maximum length of the longest common substring of the two strings, assuming my f () method is to find the largest common substring of two strings, compare them from the beginning, and if they are equal,Continue to call this method, so that the length of the recursion +1, if not equal, as long as the comparison S1 truncated one and S2 comparison, and S

Longest palindromic Substringfirst, the topic is as follows:Given A stringS, find the longest palindromic substring inS. Assume that maximum length ofSis, and there exists one unique longest palindromic substring.The topic requires the maximum symmetric substring of a given string, such as "AAABCCBACC", the maximum symmetric substring of "ABCCBA". second, the ide

Topic Link: https://leetcode.com/problems/longest-substring-without-repeating-characters/ Topic: Given a string, find the length of the longest substring without repeating characters. Examples: Given "ABCABCBB", the answer is "ABC" and which the length is 3. Given "BBBBB", the answer is ' B ', with the length of 1. Given "Pwwkew", the answer is ' Wke ', with the length of 3. Note that the answer must to be

This article illustrates the Java implementation method for finding the largest common substring of two strings. Share to everyone for your reference, specific as follows: Recently, there is a need for text comparison in the project work, after this period of study, summed up this blog content: To find two strings of the largest common substring. algorithm idea

This is a topic on Huawei OJ. First, if we write code in Java, Huawei OJ has the following three rules to follow, otherwise the compilation will not pass or the use case cannot pass, the rule is as follows:(1) must not have the package name, (2) The main class name can only be main, (3) can not output information unrelated to the result.Well, in accordance with the above rules, we write the code as follows (this code is not optimal, just to record the
