The important thing about dynamic is the ability to get all the methods and properties of a class, and we use the following code to print a list of methods and properties. A function call of the pure Swift class is no longer a OBJECTIVE-C runtime message, but a C + + vtable that determines which function is called at compile time, so it is impossible to get the method or property through runtime. TESTSWIFTVC inherits from UIViewController , the base class is NSObject , and swift in

Test instructions: Given a string that lets you turn it into a palindrome, add a minimum number of characters.Analysis: Dynamic planning is very obvious, is not the current thinking, or ask others just know, oh, originally either write, since it is palindrome string,So the final pros and cons have to be the same, so we have to ask for LCS, so that the public to find out, then use the total minus this LCS,Th

Title: Give n Strings, and each string contains a unique letter, that is, there is no "ABCA" (a repetition), and "AFDSG" is correct. Find the common letters of n strings. Finally, the output is in dictionary order. Analysis: First of all the strings of the dictionary ordering, and then ask all the LCS, the practice is 22-phase reques

LCS: two sequences S1 and S2 are given. The largest public part of these two sequences S3 is the longest public subsequence of S1 and S2. PUBLIC PART It must appear in the same order, but it does not need to be continuous. LCS has the optimal sub-structure and satisfies the overlapping sub-problems. Therefore, we can use dynamic planning to solve the LCS problem.

Note the difference between the longest common substring (longest commonsubstring) and the longest common subsequence (Longestcommon subsequence, LCS): a substring (Substring) is a contiguous part of a string, A subsequence (subsequence) is a new sequence obtained by removing any element from a sequence without altering the order of the sequence, or, more simply, the position of the character of the former (substring) must be continuous, and the latte

You need to output them and string S. s1 is a sub-sequence of S, S2 is a sub-sequence of S, and s is the shortest string that meets the preceding requirements. Analysis: For example, DP [I] [J] = X indicates that the length of the

I just introduced the weak LCS (longest common substring), and now I want to introduce an application of its powerful functions. First, let's take a look at the question: [Title Description] (vijos1327) A return word is a symmetric string-that is, a return word reads from left to right and reads from right to left to get the same result. Any given string can be converted into a return word by inserting several characters. Your task is to write a pro

Sample InputSample Outputthe meaning of the title is:Given two strings A, b, where two of the letters 22 correspond to a weight, and two strings can be arbitrarily added spaces, so that more characters can correspond, such as given two genes AGTGATG and Gttag, can be writtenAgtgat-g-gt--tagThe final corresponding weights are the score of the alignment above is (-3) +5+5+ (-2) + (-3) +

DescriptionAlice and Bob want to go on holiday. Each of them have planned a route, which is a list of the cities to being visited in a given order. A route may contain a city more than once.As they want to travel together, they has to agree on a common route. None wants to change the order of the cities on his or hers route or add other cities. Therefore they has no choice but to remove some cities from the route. Of course the common route should be as long as possible.There is exactly-cities i

The longest common subsequence (LCS) is the classic DP problem, which is the LCS of the sequence A[1...N], b[1..m].The status is Dp[i][j], which represents the LCS of A[1..I],B[1..J].The DP transfer equation isdp[i][j]=Dp[i-1][j-1]+1, a[i] = = B[j]max{dp[i][j-1], Dp[i-1][j]}, a[i]! = B[i]----------------------------------------------------------------------------
