The main effect of the topic: To the n edge, to make these edges into a triangle, ask what is the largest area? All sides must be used. Ideas: For triangles with known perimeter, we can get the equation of state by knowing that the length of the

"The main effect of the topic" There is a recursive code: Go (int dep, int n, int m) Begin Output the value of DEP. If DEP End The key is to see line fourth, if the conditional DEP Ideas For each X "I", can only take 0 or 1, in each layer

"The main effect of the topic" To put n bombs on the axes, each of the two positions can be selected to be placed in one position, each bomb can control its explosion range (to place the radius of the center of the Circle of R), ask the maximum

The main effect of the topic: To a string of n capitals, select as many strings as possible so that each uppercase letter can appear even several times. Ideas: At the sight of time limit:18.000 seconds, very high without any optimization of

"The main effect of the topic" You're listening to the music player, which takes the form of random playback. The principle of random playback first randomly produces a 1~n arrangement, and then in this order to play the song. After playing all the

"The main effect of the topic" Assuming you already know an array of a[n], then use the function to generate a matrix B: void calculate (int a[n], int b[n][n]) {for (int i = 0; i for (int j = 0; j if (i = = j) B[i][j] = 0;else if (i% 2 = 1 && J% 2

QT allows you to create your own event types, which are especially useful in multithreaded programs, and, of course, can be used in single-threaded programs as a mechanism for communicating between objects. So why do I need to use the event instead

Today we're talking about the event () function. Remember that this function has been mentioned before, that QT passes this event object to the Qobject event () function after it has been created. The event () function does not directly handle

Attention: This article contains sample sources that refer to the Pro LINQ book from Joseph C. Rattz, Jr. Lambda expressions are introduced by MS in C # 3.0. The lambda expression was first seen in the Lisp language, which was conceptualized by

In the data query, we often encounter the need to dynamically build query conditions. Implementing this requirement with LINQ can be a bit more cumbersome than the previous concatenation of SQL statements. This paper introduces 3 kinds of methods of

This article describes the interface description and usage of the. NET collection type, which is simple enough to clarify the idea and the use specification of the collection type as a parameter and return value, and more discussion about the

Take a detailed look at the execution of the Invokeaction method: protected internal bool Invokeaction (string actionname) { return invokeaction (ActionName, New routevalued Ictionary ()); 　　　　　　} Protected internal virtual bool Invokeaction

Summary: The membership component of ASP.net 2.0 provides a very easy-to-use set of interfaces for user management and user authentication by developers. This paper makes a simple analysis of its implementation principle, and describes how to use it

8. Implement Idictionary interface Because the front implementation of the IDictionary interface, now realize Idictionary also have no difficulty, divert. First change the class declaration: public class ReversibleSortedList :IDictionary

One, reference type equality comparison: A total of four comparison methods: 1:referenceequals () method, static method, that tests whether two references specify the same object. And that null equals NULL. 1 Class1 x,y;2 x = new Class1 ();3 y =

Unlike the real world, in the programming world, everything is black or white, right or wrong, true or false. For example, suppose you create an integer variable named x, assign the value 99 to X, and then ask, "Does x contain a value of 99?" "The

A prime number is divisible only by 1 or itself, and cannot be the product of two other integers. 1, 2, 3 itself is prime, to determine whether a number is prime, just use this value divided by 2 to its root number, if there is a number divisible,
