我们考虑,一个子串必定是某个后缀的前缀。 排序相邻的后缀他们的前缀一定最相似。 所以全部的一种子串必定是一些排序相邻的后缀的公共前缀。 从l开始的子串,则从rank[l]开始看,两侧height ...
来自http://www.cnblogs.com/oa414/archive/2011/07/21/2113234.html的启发, 看上述博客如何求第k大的数时,被其第二份代码影响,感觉很巧妙,于是研究了一下,搞懂后顿时神清气爽啊。。。 还是看这张经典的图吧,知识在图上就变得 ...
在未排序的数组中找到第 k 个最大的元素。请注意,你需要找的是数组排序后的第 k 个最大的元素,而不是第 k 个不同的元素。 示例 1: 示例 2: TopK的问题,思路就是用堆来解决。 先以前K个元素构建一个大小为K的小顶堆,然后从K个元素之后,遍历从索引在K后面的元素 ...
