Using arrays to implement stacks and queue fighting Spirit Queue Song queue study queue

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. arrayarrayarrayNULL。 此外如果被调用不是一个数则会产生一个 Warning。 $stack = array("orange", "banana", "apple", "raspberry");$fruit = array_pop($stack

Queue implementation: cyclic queue and chained queue

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

Queue, chain queue, chain storage 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. This example uses t
