LeetCode 215. Kth Largest Element in an Array(排序) 题目 题意:找到一个数组里第K大的数字。 题解:我们当然可以排序好了,之后,选择第K大的数字。但是这样做一点技术含量也没有。 AI检测代码解析 排序算法选用快排。寻找第K大的数字,不必把数组完全排完序之后,再找第K大。快排中是选取一个...
An analog circuit is devised which selects and outputs the kth largest element among n input voltages. The circuit is composed of n basic transconductance amplifiers connected mutually with an O(n) length wire, thus the complexity of the circuit is O(n). The circuit becomes particularly simple...
