力扣链接:leetcode.com/problems/k 博主Grandyang的c++解法:[LeetCode] 215. Kth Largest Element in an Array 数组中第k大的数字 开始的时候我的脑子里产生了很多天马行空的想法,比如用一个queue去重新存放顺序之类的。但是那显然是不合理且乱糟糟的。kth largest,就是一个排序问题。这里又一次用到了分治法,...
这个题是在无序数组中找经过排序后的中间位置的值。实际上这个题和Kth Largest Element in an Array差不多,Kth Largest Element in an Array是求第k大,这个题是限定了k是中间位置,并且要求时间复杂度是O(n),所以使用partition的方式就可以。 时间复杂度分析: https://rcoh.me/posts/linear-time-median-findin...

Given a sorted integer array arr, two integers k and x, return the k closest integers to x in the array. The result should also be sorted in ascending order. An integer a is closer to x than an integer b if: |a - x| < |b - x|, or |a - x| == |b - x| and a < b...
