The difference between the longest common sub-sequence the longest common substring in first science:Find the longest common substring of two strings, which is required to be contiguous in the original string. The longest common sub-sequence does not require continuo

D 1. the maximum length of the subsequence after the string is deleted 1. Problem Description Please delete several characters in the string "uxdqir1_jeuuryhkntuvpbyidyxqcxitpvsnskwjiijtz", and the remaining characters constitute a child sequence (that is, the sequence starts from 2nd characters, the ASCII code of each character is not less than the ASCII code of the previous character ). Calculates the longest subsequence without downgrading. 2. Key

1. What is LCSS? What is LCSS? Many Bo friends see these letters may be confused, because this is my own on the two common questions, They are the longest common sub-sequence problem (longest-common-subsequence) and the longest common substring (longest-common-substring) problem, respectively. These two problems are ve

(1) Find the longest common substring of two strings Question: enter two strings to find the longest common substring in the two strings. Find the longest common substring of two strings, which must be continuous in the original string. Therefore, we use a two-dimensional matrix to store intermediate results. How can we construct this two-dimensional array? Assum

Given a string, find the length of the longest substring without repeating characters. For example, the longest substring without repeating letters for "ABCABCBB" are "abc", which the length is 3. For "bbbbb" the longest substring are "B", with the length of 1.Solution One: Enumerate all substrings of a string, remove the part with repeated characters, and finall

Dynamic Programming Complex problems often occur. Instead of simply breaking down them into several subproblems, they may break down a series of subproblems. Simply resolve a large problem into a sub-problem, and combine the sub-problem solution to export the solution of the big problem. the time consumed for solving the problem increases in a power series according to the scale of the problem. To reduce the time required to repeatedly find the same subproblem, an array is introduced, no matter

Preface before HANLP use "shortest editing distance" to do the recommender, the effect needs to be improved, the main disadvantage is that according to the pinyin sequence of the editing distance recommended, the same word interleaved is very common, and the editing distance is not so large. I was looking for a complementary scoring algorithm to judge how similar the two sentences were to this dimension of pinyin. The difference between the longest co

Given a string, find the length of the longest substring without repeating characters. For example, the longest substring without repeating letters for "ABCABCBB" are "abc", which the length is 3. For "bbbbb" the longest substring are "B", with the length of 1.The problem of finding the longest non-repeating substring

Topic:Given A stringS, find the longest palindromic substring inS. Assume that maximum length ofSis, and there exists one unique longest palindromic substring.idea: The title requires a longest palindrome substring of S. The brute force solution is to enumerate all the substrings and then make a palindrome judgment on each substring. For pruning, we consider the

I need to write an algorithm in my work recently, and I have found a very interesting thing when I finish writing this algorithm. The algorithm needed is this: for A, b two string, find up to K common substrings, making this K substring length and maximum. At first, I thought about some messy ideas.Error 1: For example, each time you find the longest common substring, find a substring, delete the substring from a A, b two string, and then find the
