1.定义 栈:后进先出(LIFO-last in first out):最后插入的元素最先出来. 队列:先进先出(FIFO-first in first out):最先插入的元素最先出来. 2.用数组实现栈和队列 实现栈: 由于数组大小未知,如果每次插入元素都扩展一次数据(每次扩展都意味着构建一个新数组,然后把旧数组复制给新数组),那么性能消耗相当严重. 这里使用贪心算法,数组每次被填满后,加入下一个元素时,把数组拓展成现有数组的两倍大小. 每次移除元素时,检测数组空余空间有多少.当数组里的元素

Katalon---一款好用的selenium自动化测试插件 selenium框架是目前使用较广泛的开源自动化框架,一款好的.基于界面的录制工具对于初学者来说可以快速入门:对于老手来说可以提高开发自动化脚本的效率.我们知道Selenium IDE是一款使用较多的脚本录制工具,且只支持Firefox老版本.今天给大家介绍一款Selenium IDE的替代者,Katalon Automation Recorde 如下为安装使用方法: 1.安装去谷歌应用商店,或者火狐插件均可下载 2.使用方法 2.1

1.函数的作用:返回数组当前元素位置的下一个元素 2.函数的参数: @param array &$array 3. 例子一:数组拷贝时,内部指针的位置也一起拷贝 <?php $arr1 = ['last','next']; next($arr1); $arr2 = $arr1; echo "Pointer of arr1 is " .key($arr1) .". The value is '" . current($arr1) ."'\n&q

在使用queryselector获取一个dom元素,编译时却报错说property 'style' does not exist on type 'element'. 原因:这是typescript的类型检查导致的,需要在querySelector方法前面加个类型断言. let frameContainObj = document.getElementById("model_view_container") let iframeObj= <HTMLElement>frame
