1. Question: Use two stacks to implement a queue. First use a stack to enter data, and then output this stack to another stack to form a first-in-first-out order for the queue.
Because PHP’s array can simulate the implementation of a stack, the code is as follows:
<?php
function StackToQueue($data)
{
$arr=array();
while($_t=array_pop($data))
{
array_push($arr, $_t);
}
return $arr;
}
$a=array();
for($i=1;$i<=5;$i++)
{
array_push($a, $i);
}
var_dump($a);
$a=StackToQueue($a);
var_dump($a);Copyright Statement: This article is an original article by the blogger and may not be reproduced without the blogger's permission.
The above introduces queues and stacks: two stacks implement queues, and two queues implement stacks, including aspects of the content. I hope it will be helpful to friends who are interested in PHP tutorials.
