Without recursive implementation of the infinite level of classification, a simple test of performance than recursion a little bit better, but write too complex, or recursive simple convenient point Code: 1, ' pid ' =>0, ' deep ' =>0, ' name

The example in this article describes the way to implement an infinite loop for the Go language simulation while statement. Share to everyone for your reference. The implementation methods are as follows: This code uses the For statement as a while

There are roughly three ways to type PHP's infinite categories, 1, the database by setting the parent class ID to make a unique index, and then use the function of recursive calls to achieve an infinite classification; 2, database design through a

This article mainly introduces the implementation of JQuery asynchronous loading of the infinite drop-down box cascade function. For more information, see The Code is as follows: /*JQuery asynchronously loads the infinite pole drop-down box

XML is as follows: The function originally intended to be implemented is to make the transparency from 0 to 1, wait for 2 seconds, and then let the transparency from 1 to 0 to achieve the goal of flashing; the advantage of doing so is

Given any D, it is the probability that some H's bad Sample (i.e. Ein and eout are not close) is:That is, the number of alternative functions in H m=| H| The less the sample data is, the smaller the probability of the sample becoming a bad sample.
