对称MVD模式(symmetric MVD mode)是VVC中新提出的一种双向预测时MVD语法单元传输模式。在使用对称MVD模式时，在传输双向预测的运动信息时不需要传list0和list1中参考图像的索引和list1的MVD。这些信息可以在解码端生成。对称MVD模式的解码过程如下：1、在slice层，变量BiDirPredFlag, RefIdxSymL0和RefIdxSymL1按如下方...

Qt开发-MVD架构模型/视图类MVC是一种我们熟知的架构模式，它的全称是 Model View Controller。MVC具体的概念及应用，网上已经非常非常详尽了，这里就不赘述了，今天要了解的是其在Qt中的具体应用。Qt中的MVC并不叫MVC，而是叫MVD，Qt中没有Controller的说法，而是使用了另外一种抽象: Delegate (委托) ，其行为和传统的MVC是相同的。模型(Mode

创建一个函数，接受两个或多个数组，返回所给数组的 对等差分(symmetric difference) (△ or ⊕)数组.给出两个集合 (如集合 A = {1, 2, 3} 和集合 B = {2, 3, 4}), 而数学术语 "对等差分" 的集合就是指由所有只在两个集合其中之一的元素组成的集合(A △ B = C = {1, 4}). 对于传入的额外集合 (如 D = {2, 3}), 你...

这里A这道题的时候，刚看到题目的时候想到用递归。后面题目也有提示，用递归或迭代。还是没有弄出来，主要参考了http://www.cnblogs.com/remlostime/archive/2012/11/15/2772230.htmlLeetCode Oj:https://oj.leetcode....

前言：【pair的简介】：1、它是一种模板类型的结构体，定义在头文件#include<utility>template<class T1,class T2>2、有两个成员是first,second3、模板参数可以是任何类型的【STL简单提要】：1、分为序列式容器和关联式容器1）序列式容器就是里面操作的数据无关联，比如：vector，它的操作push,pop2）关联式容器就是

一、前言传统的模型-视图框架可以让我们实现逻辑个展示相分离，我们只需要关心模型就可以，在模型上做的任何更改都会走动更新到视图上去，其实就是观察者模式。Qt基于传统的模型-视图框架（MVC，model、view、controler），推出了MVD(model、view、delegate)框架。具体有什么用呢？如果我们使用QTableView来作为表格控件，显示数据，
