Very good PHP coding specifications. note: This shows the coding specifications from the PHPCMS development documentation. Although the code is called the PHPCMS development specification, I think this applies to all PHP programming. After writing so many PHP codes, many codes may not be able to compare and correct the codes in the future.

Question 21: programming, input two integers n and m, from Series 1, 2, 3 ,...... N is random, so that the sum is equal to m. All possible combinations are required. It is actually a backpack problem. Solution: 1. First, determine that if nm is used, the number of n greater than m cannot be involved in the combination, and then set it to nm; 2. Add the maximum nu

Title: Input positive integer n, output 1+2+3+...+n value. Tip: The goal is to solve the problem rather than practice programmingIn order to output 1+2+3+...+n, you can use the first item plus the last item multiplied by the number of items divided by the 2 formula(1) Declar

(11x11,5x5) in Alexnet. For a given field of perception (the local size of the input image associated with the output), the use of a stacked small convolution core is preferable to a large convolution core, since multilayer nonlinear layers can increase the network depth to ensure a more complex pattern of learning, and the cost is smaller (fewer parameters). For example, the 3-step 1 3x3 convolution nucle
In the PHP language, for digital characters and numbers how to participate in the operation, in specific cases will be determined, for example: echo "3+4+5"; Results: 3+4+5. Because it is treated as a string. When echo1+2+ "3+4+5", it is treated as an expression. This involves the problem of different data type operations in PHP. Data of different data types when
