  The first of the three major paradigms of database design is that the independent table structure must have a unique primary key to identify the table data. in the past, Microsoft's SQL Server (duo version) platform. manually encode the primary

InOracle DatabaseWhat isSequenceWhat about it? What is its purpose? SEQUENCE is actually a serial number generator. It can automatically generate a serial number for rows in the table and generate a set of values with equal intervals (numbers ). Its

  Limited to your own level, you may have many questions, but you may still have such shortcomings. Some questions are not as many as some "hit questions" as they are after the competition ", I also hope you will forgive O (∩ _ ∩) O ~. My

Old Zhao's post Abstract: The sum of all positive integers that divide sum into N. Each positive integer k must meet the following requirements: min The N integers can be repeated. However, because of the addition exchange rate, 1 + 2 and 2 + 1

Ideas: The push and pop operations are completed within the constant time complexity. However, the min operation must be completed within the constant time complexity. At first, it is easy to think of saving a variable min in the stack, to save the

Rmq (range minimum/maximum query) problems:The rmq problem is the most important problem in the given range. Of course, the simplest algorithm is O (n), but the O (n) algorithm is not efficient enough for queries with a large number of times (up to 1

Description Give you A matrix A (0 Input Multiple groups of test data. The first is the number of data groups T For each group of test data, the first row is two positive integers m, n, indicating the number of rows and columns of the matrix

This article mainly introduces a stack interview question solved by PHP. the high-end PHP programmers who are preparing for the interview can look at it. if you need it, you can refer Preface When I encounter an interview question, the question is

This article mainly describes the differences between offsetHeight, clientHeight, and scrollHeight. If you need them, you can refer to them. I hope you can find some help on the Internet. The conclusion is very general, I never talked about IE

For a common sorting algorithm, it is difficult to sort in O (n) time, and the space complexity is O (1), here is a way to achieve the requirements.You can use the idea of hash sorting, which is to hash all the numbers into a hash table and

Gister 1th article.The basis is the element that determines the composition of the skill. The building is not good because the foundation is not strong, skills are also so.Let's talk about the pits I've stepped on in the base.Java knows there are 8

1 n-bit positive integer A, delete the K-bit in it, get a new positive integer b, design a greedy algorithm, and get the smallest b for a given and K;I think: First look at the example: a=5476579228; remove 4 bits, then the number of digits n=10,k=4,

Search on the Internet, the conclusion is very general, speak IE never speak version, so they did the test and upload the conclusion. The conclusion is that the test is passed in standard mode, and there is no test quirk mode. ClientHeight Most

a primitive type, or a built-in type, is a special type that differs from a class in Java. They are the most frequently used types in our programming, so they are always in the interview question, and in this article we will review the basic types

Today we continue to introduce a sort algorithm: select sort.The basic idea of selecting a sort is to select the smallest one from the sequence to be sorted, and then swap the position of the selected element with the first element of the sequence
