Php lottery and random ad algorithm we will first complete the PHP process in the background. The main task of PHP is to configure the awards and the corresponding winning probability, when the front-end page clicks a box, it will want PHP to send ajax requests in the background. then, the background PHP will give the winning result through the probability algorithm based on the configured probability, at the same time, the outstanding award informati

General idea:Add the number to the ArrayList dynamic array, use the static method of the set collections.shuffle () the elements in the sequence set to get the random number,remove Delete a drawn number The code is as follows:1 Importjava.util.ArrayList;2 Importjava.util.Collections;3 ImportJava.util.Random;4 5 Public classRaffle {6 7 PrivateArraylistlist;8 9 Private voiddeal () {Ten //adds a specified number of num integers to the list container in order One if(li

Two-color ball lottery random algorithm-Java implementation, two-color ball algorithm-java The first time I wrote a technical blog, I wrote a random two-color ball lottery algorithm. The principle is as follows: 1. Initialize an array nums to be drawn, whose length is k. 2. Random number ranging from 1 to k, and obtain nums [k]. In this way, the first lucky draw number is obtained. Remove this number from n

Recently, the project requires a lottery turntable function. It takes a long time to draw the background, text, and image of each item, it will not catch up with the progress of the project, so it is a coincidence that the award and the turntable pointer are regarded as an independent whole, and only the rotation and angle judgment can be done, which will save a lot of time, even if you want to update the lottery
