问题 I'm using Node/Express to make API requests to the unofficial Vine API. The data that the GET https://api.vineapp.com/users/search/ route returns changes on parsing. My code is the following: request({ url: 'https://api.vineapp.com/users/search/' + username }, function (error, response, body) { if (error) throw new Error(error); console.log(typeof body,'UNPARSED BODY:', body); body = JSON.parse(body); console.log(typeof body,'PARSED BODY:', JSON.stringify(body, null, 2)); cb(null, body) });

二叉查找树的平衡(DSW算法)

时光总嘲笑我的痴心妄想 提交于 2020-12-17 08:54:07
树适合于表示某些领域的层次结构(比如Linux的文件目录结构),使用树进行查找比使用链表快的多,理想情况下树的查找复杂度 O(log(N)) ,而链表为 O(N) ,但理想情况指的是什么情况呢?一般指树是完全平衡的时候。哪最坏的情况是什么呢?就是树退化为链表的时,这时候查找的复杂度与链表相同。就失去了树结构的意义。所以树的平衡是非常重要的,这一节我们主要讨论树的平衡问题。 <u>如果树中任一节点的两个子树的高度差为0或者1,该二叉树就是高度平衡的。</u> 上图中,A是平衡二叉搜索树,B是不平衡的,C直接退化为链表了。 为保持树的平衡,有两种策略,一种是全局的,即当插入和删除操作完毕后,对树进行重建,全局调整树为平衡树;另一种是局部调整,即当插入或者删除导致树不平衡时就立即在局部范围内调整,使树保持平衡,这个是后面要讨论的AVL树。下面我们先讨论一下全局调整的方法。 有序数组创建二叉查找树 要想实现树的平衡,最简单的想法是我们可以设想一下将树的所有节点从小到大排序后,将中间值作为根节点,左侧的值作为左子树,右侧的所有值作为右子树,每个子树再按根节点的划分方法,以此类推,代码表示如下: // data是排序后的数组 template<class T> void BST<T>::balance (T data[], int first, int last) { if (first <=

Twitter截胡微软,已与TikTok的潜在合并交易进行了初步商谈

      大数据文摘出品    来源:WSJ    编译:刘俊寰   微软能否顺利收购TikTok尚未确定,如今,TikTok收购又迎来了一位“竞标者”。   根据《华尔街日报》报道,Twitter已经与TikTok进行了初步的谈判,但目前尚不清楚两家公司的最终意愿。   不过,不管是微软还是Twitter,在特朗普政府的强压之下, TikTok的在美国的业务势必都会受到一定程度的影响 。      根据知情人士爆料,微软已经与TikTok母公司字节跳动进行了长达数周的谈判,外界普遍认为微软会是这项交易的最终达成者,Twitter的加入并不能改变当前的局势,不管是在金额还是在时间上,相比微软, Twitter的交易成功率都要小得多 。   8月2日,微软首席执行官Satya Nadella与特朗普讨论了关于TikTok收购方面的事宜,并表示,正在就TikTok在美国、澳大利亚、加拿大和新西兰的业务进行谈判。   特朗普上周表示,TikTok必须在9月15日之前为其美国业务寻找买家,否则将面临禁令。   Twitter收购TikTok,是“蛇吞象”?   目前,Twitter的市值约为290亿美元,微软的市值超过1.6万亿美元。   TikTok在美国的业务估值走势也逐渐不容乐观,上周,TikTok的估值已经从500亿美元下降到了100-300亿美元,但这对于Twitter来说

How to get Vine video url

我怕爱的太早我们不能终老 提交于 2019-12-18 11:12:34
问题 I love vinepeek and want to make something better. I have the Vine link e.g. http://vine.co/v/bJqWrOHjMmU , however this is a link to a page, not the video URL. I know it's new, but does Vine have an API, or how else would I be able to get the url of the video? I'm still puzzled as to how Vinepeek gets the video url? 回答1: It is in the page source; you could parse it with a JavaScript bookmarklet function qry(sr) { var qa = []; for (var prs of sr.split('&')) { var pra = prs.split('='); qa[pra
