I have never understood the LCS problem before. However, the problem of finding a job being tortured by LCs is lost with that company. The longest common subsequence problem is a classic dynamic programming problem. The longest common subsequence problem also has the optimal substructure. That is: xi If: XM = yn (the last character is the same), it is not difficult to prove that this character must be any of the longest common subsequences of X and y

Dynamic Planning Algorithm for Solving LCS Problems 1 Structure of the longest common subsequence The structure of the longest common subsequence is as follows: Set sequence X = 1> If xm = yn, zk = xm = yn, and Zk-1 is the longest common subsequence of Xm-1 and Yn-1; 2> If xm =yn and zk =

1. Longest Common subsequence Problem Description The subsequence of a given sequence is the sequence obtained after several elements are deleted from the sequence. To be exact, if the given sequence X = {x1, x2 ,... xm}, then another sequence, Y = {y1, y2 ..., yn}. When another sequence is the subsequence of X and the subsequence of Y, Z is the public subsequence of X and Y. The longest common subsequence problem is the given sequence X and Y. Find t

Recently, I encountered an ultra-poor SQL statement. The table name is processed because the SQL statement involves data from a certain tax bureau. The original SQL statement is as follows: Select * from (select T. zxid, T. GH, T. XM, T. BM, T. fzjtpd, (select count (. session_id) from test_v A where to_char (T. zxid) =. zcryzh) slzl, (select count (. session_id) from test_v A where to_char (T. zxid) =. zcryzh and.

Not long ago, I saw an article on configuring the database connection pool in Tomcat on the blog of l_xiaodao. I tried to configure the database twice as described in the following comparison: I tried sqlserver database once, the other is the Oracle database. The configuration process is described as follows: My tomcat version is 5.0.25. First create a directory D:/test in disk D, then create the WEB-INF directory under test, create the classes directory and lib directory under the WEB-INF direc

In essence, it also adopts the idea of stepping. However, it is optimized compared with the DDA algorithm to avoid floating-point calculation during step-by-step operations, and provides a good idea for selecting points that conform to the linear equation. First, the slope of the straight line determines whether to perform th

　　This essay mainly introduces the implementation of a simple decorator design pattern in Java:First look at the class diagram of the adorner design pattern:　　　　As you can see, we can decorate any implementation class of the component interface, and these implementation classes also include the adorner itself, and the adorner itself can be decorated again.The following is a simple decorator design pattern implemented in Java, which provides the basics of adding coffee and can continue to add mil

the size (in bytes) of each element of the array to be sortedPfcompare is a function pointer that points to a "comparison function."The use of the Qsort function stipulates that the prototype of the "comparison function" should be:int functionname (const void * elem1, const void * elem2);Elem1 and Elem, pointing to the two elements to compare.* Elem1 and * elem2 are the two elements to compare.The function must have the following behavior:1) If * elem1 should be in front of * elem2, then the fu

Longest Common subsequence of LCS and LCS common subsequence Problem: The Longest Common subsequence does not require that the obtained string be continuous in the given string. For example, the input two strings ABCBDAB and BDCABA, And the strings BCBA and BDAB are both their public longest headers. This is a dynamic planning problem. Answer: set sequence X = 1) if xm = yn, there must be zk = xm = yn, the
