Most of the time, Lis uses a two-point method to make it easier to write his principles here.This is only a discussion of the strictly longest ascending sub-sequence.There are two numbers. A sequence is the sequence of the original string A1-an another sequence is the longest ascending subsequence auxiliary series s sequence length k, which is the longest ascending subsequence length of the currentLet's take a look at the N*

One-to-many association relationshipCorrelation characteristics: 1 of the party has n the one side of the collection attribute, N of the party does not have 1 of the side of the referenceFor example, if the customer has a one-to-many association with order, the customer has an order collection attribute, and the order does not have a reference to the customer. This allows the customer to retrieve all of the

/* Input two numbers m and N, select several of these numbers from the sequence 1,2,3,4,..... N and for M, find all of such combinations */void findsum (int m,intn,vectorThis is a typical knapsack problem, for such problems, the main thing is to clear the mind, is not in line with the knapsack principle, and then find the appropriate solution. At the same time you need to understand how to deal with boundar

PHP generates n non-repeating random numbers, PHP generates n random numbers Cause: There are 25 pieces to vote, one to vote for 16, and one to vote only once per piece. In front of a programmer stabbed blunder, forgot to put the vote in the library, there are 200 user-generated voting sequence is empty. So how would you fill this blunder? Certainly reflect the situation to the superiors. But what we're ta

[i, l] = sum bord[i, j]-sum B[l, j] If L = k, the contradiction is not established, the original proposition is correct.The BSA array records the largest sub-array in [0, I], while border is the largest subarray of the right boundary of i + 1, and if sum border > sum BSA, Border becomes BSA. This completes the lookup of the maximum subarray of BSA for the entire array in a single traversal, the time complexity is O (n), and the subsequent verification

Explore n in char/varchar (n): number of characters or bytes, number of varchar bytes [Problem source] When I display the database table designed, yu asked me, why is the top_info field of your top_info defined type varchar (100) 100, how many Chinese characters can be stored in the length of 100? At that time, the idea was that there was a correlation between how much text can be stored in this 100 databas
