Graph Structure Graph Definition theano's symbolic mathematical computation, which is composed of: Apply node: the application of an operator to some variable. Variable node: symbolic varibles. Op node: mathematical operation like: +,-,*,\,sqrt,sum,t…

In this tutorial, we will learn about DOM querying and how the dojo/query module allows you to easily select nodes and work with them. 在本教程中,我们将学习DOM查询,并且使用dojo/query模块,更容易的选择几点,并完成相关操纵. Getting Started 开始 When working with the DOM, it's important to…

dom.byId require(["dojo/dom", "dojo/domReady!"], function(dom) { var one = dom.byId("one"); function setText(node, text){ node = dom.byId(node); node.innerHTML = text; } setText(one, "One has been set"); setText(&qu…

D 插入: 在当前指针位置sz处插入一个1,col[sz]记录插入的内容,sz++; 删除i: 找到第i个1的位置,赋为0; 于是转化为一个维护区间和的问题; trick: 如果是依次删除a[0],a[1]...a[k], 那么对应的删除操作应该为 a[0],a[1]-1,a[2]-2...a[k]-k,要把前面删掉的算进去; #define maxn 1000100 int bit[maxn],a[maxn],n,m,col[maxn],sz; int lowbit(int x){return…

前言: 前面两章讲了dojo的基本规范和配置,当然这个配置不是必须的,当你有这需求的时候就可以用到dojo的config配置. dojo的所有js都是符合AMD规范进行异步加载的:http://blog.csdn.net/eguid_1/article/details/52083016 并且详细阐述了dojo的config设置:http://blog.csdn.net/eguid_1/article/details/52092016 缀述: 这章开始真正讲解dojo的所有基本操作,包含dom.q…

Given an undirected graph, return true if and only if it is bipartite. Recall that a graph is bipartite if we can split it's set of nodes into two independent subsets A and B such that every edge in the graph has one node in A and another node in B.…

https://github.com/xieqing/red-black-tree A Red-black Tree Implementation In C There are several choices when implementing red-black trees: store parent reference or not recursive or non-recursive (iterative) do top-down splits or bottom-up splits (o…

Description http://www.lydsy.com/JudgeOnline/upload/Noi2017D2.pdf Solution 网上大部分都是并查集写法,但是有大神写了非并查集写法,特别容易理解 首先 \(s_i\) 的限制,只需将每一个蔬菜分出一个价值为 \(a_i+s_i\) 且过期时间为该蔬菜最晚的一天的蔬菜 把时间倒序之后,问题转化为每个蔬菜会在第几天出现,每天贪心选择价值最大的即可 先求出 \(\max \{p_i \}\) 的答案,然后递推 \([1,\max…
