(困难) CF 484E Sign on Fence，整体二分+线段树

Codeforces 484E. Sign on Fence 可持久化线段树
大概题意: 给一数组a,问在某一区间L~R中,问对于连续的长为W的一段中最小的数字的最大值是多少. 显然可以转化成二分高度然后判断可行性的问题. 考虑到高度肯定为数组中的某一个值,将数组从大到小排序. 建n棵线段树,对于第 i 棵线段树,将 大于等于a[i] 的叶子的值设置为1,其他的叶子设置为0,问题就转化成了用线段树求某一区间中最长的连续的1的个数,这是一个线段树的经典问题,可以通过维护每个节点的 左边连续和,右边连续和,连续和的最大值 得到. 由于空间问题,不可能建立10^5棵线段树,考虑

接口sign验证
在爬虫快手主播信息的时候,发现只要我改动一下参数,比如第一页 page=1的时候,需要爬下一页,把page改为2发现提示sign验证失败了 也就是说,快手在开发的时候考虑了有人抓包到接口后,通过修改参数的方式继续获取下一页(或者是其他操作,总结就是防止用户截断请求修改数据包后提交的做法) 我估计做法大概是在调用接口前,先对所有参数进行一个md5,当用户改一下值后,md5 出来的值就不对了 然后具体它md5了哪些值,没法得知,所以,尼玛靠接口采集有点悬.... 但是后来发现,每次我发送同一个参数过
