throw statement is required to complete the process where the original RAISERROR need to assign a variable and pass the argument to the throw exception. Also, the capture of the error line points directly to the error line, rather than the line of code that occurs when the RAISERROR statement takes place like RAISERROR. And throw can be as raiserror as can be passed, the effect and RAISERROR are the same.The summary is that RAISERROR can do the throw can be done, and throw can also save RAISERR

A queue is an ordered set that complies with the FIFO principle.Add new elements to the end of the queue and remove elements from the top.

Array_push () can implement the PHP language stack function.
array_push()函数的使用心得1.第一个参数必须是数组。2.所有添加的数组均为索引,即数组下标。3.$num为压入后$stack所含数组元素的个数。4.使用数组的直接赋值也可以实现数组的进栈功能,例如$array$key。$num = array_push($stack"C#""Ruby"array('jsp''Asp'),array('jsp''Asp'));
Array_pop () can implement the queue function of the PHP language.

Today, I am very depressed. It was nearly a day before I finally figured out what queue is. Although I learned from myself when I used to take the computer Level 3, I learned from the data structure class, And the queue is FIFO. However, many problems have been discovered only by writing a queue (cyclic queue) by mysel
There are two types of linear tables with limited access locations: Stack and queue. There are two ways to implement Queues: sequential and chained.
Cyclic queues are implemented in order. Two variables, front and rear, are used to record the header and tail of the queue. The implementation code is as follows:
Class cqueueimpl {Cqueueimpl: cqueueimpl (INT size) {
In the implementation of cyclic queues, it
[Algorithm design-priority queue] implementation and operation of priority queue, algorithm queue
Priority queue is a specific application of heap sorting.
Priority Queues are divided into the following operations:
1. INSERT (S, x) inserts element x into the priority queue.
A chain-based queue is called a linked queue. A queue is a linear table with limited operations, that is, the insertion and deletion of a queue are at both ends of the table. Therefore, two pointers are required to point to these two special locations, namely, the first pointer and the last pointer.
