Using Newton's Iterative method to find the root of the following equation near 1.5:2x^3-4x^2+3x-6=0
As for the Newton iterative method, in the course of computational methods, the basic formula is:
xn+1=xn-f (Xn)/F *(Xn) xn+1 is the n+1 iteration result,Xn is the nth iterat

[ModernPHP] Chapter 2 new feature 6 ZendOPcache
Zend OPcache
Bytecode caching technology is not new to PHP. We already have Alternative PHP Cache (APC), eAccelerator, ionCube, and XCache independent Extensions. they can all be used as our optional solutions. But they are not found in every core release version of PHP. Until now, PHP 5.5.0 has its built-in bytecode cache: Zend OPcache.

1. Concurrent programmingThese two nouns are concepts in concurrent programming and are defined under the model of concurrent programming:
Concurrency: It is on the same CPU at the same time (not really at the same time, but at the same time, because the CPU is switching between multiple programs) to run multiple programs.
Parallel: is multiple or simultaneous one CPU, each CPU runs a program.
For example, concurrent, like a person (CPU) Fe

6.3.3 Interactive Shell BehaviorWhen shell runs in interactive mode, its behavior changes in some aspects.1. Read and execute the Startup File according to the description in the bash Startup File section.2. Enable job control by default (see job control ).

6-2 insertion of ordered order table (10 points)
This requires the orderly insertion function of an ascending sequential table to be implemented. L is an ascending sequential order table, where the function status listinsert_sortedsq (SqList l, Elemtype e) is used to insert a data in an ascending order in the order table. For example: The original data is: 2 5,
