The specific implementation of the hash table is not much to introduce, is an array, each subscript is stored is a collision element of the linked table head pointer, as shown in:The following is a direct study of the analysis using the link method hash:Given a hash table with M slots that can hold n elements, the load factor α defining T is n/m, which is the average number of elements stored in a chain.The worst-case scenario with link hashing is poo

There is such a problem, look at the picture below, suppose there is a straight line, each fork has an ant, they will randomly select a direction, moving forward or backward, when two ants meet, they will turn around, ask: All the ants go out the longest and shortest steps;The shortest number of steps is obvious ... As long as the direction is right, it is 11;The longest ... The first reaction in the brain when you see a problem is that there is no algorithm to store the problem, and then we beg

A very common application in bullet is to call the callback function provided by the developer when two objects collide. For example, if a sphere hits another sphere to make a sound The following is an example of three types of objects in a scenario: ball (dynamic), floor (static), and wall (static) The sound of the ball hitting the wall is different from that of the floor. Therefore, you need to set these three objects to different categories and use the userpointer of collisionobj to c

Wcollision is used for collision between people in tianlong Babu and the surface of the ground object. For example, a bridge does not belong to the earth surface and belongs to an object and cannot be detected by the Terrain Height. However, if people want to pass, a transparent collision surface is built on it. I marked it with a black material ,: The data format of the wcollision binary

Thanks to an e-commerce platform security engineer Feiyu with me to discuss this bug fix. In the past, in the process of security testing, there are often problems caused by the verification code, even in some banks or e-commerce login and check the page also exists this problem, once the collision of the security of the user account or the site load is a huge challenge. In fact, the cause of the problem is not complex, mainly in the development proce

With the development of the collision game One success!Our AE lad is also daring to try out many new schemes h5.So the following is the birth of a more perverted game. Let's take a look at the tank wars.The process of development is very difficult but it's fun. Fixed a lot of mistakes and improved some ideas1. The original canvas of the _this existence of the global pollution improved to avoid 99% in order to get Windowtouch attributes or 1% of the ho

Now some scientists get the result of merging two galaxies, some of the points on the two-dimensional plane, but do not know that the

Introduction Using Osgutil::linesegmentintersector to do the line collision detection, the principle is to put the ball current position and the new position into the line and the box to do collision detection, if there is an intersection, it is not allowed to move the ball, recorded in this memo code #include ". /common/common.h "#include
