2、将Map导入到一个数组当中,对数组排序,然后算出哪个才是第k小的值。 代码如下: /** * @param {number[][]} matrix * @param {number} k * @return {number}*/varkthSmallest =function(matrix, k) { let count= 0, n =matrix.length; let myMap=newMap(); let myArr=newArray();for(let ...
Given anxnmatrix where each of the rows and columns are sorted in ascending order, find the kth smallest element in the matrix. Note that it is the kth smallest element in the sorted order, not the kth distinct element. Example: matrix = [ [ 1, 5, 9], [10, 11, 13], [12, 13,...
给定整数数组nums和整数k,请返回数组中第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。 你必须设计并实现时间复杂度为O(n)的算法解决此问题。 示例1: 输入:[3,2,1,5,6,4],k = 2输出:5 示例2: 输入:[3,2,3,1,2,4,5,5,6],k = 4输出:4 ...

Design a class to find the kth largest element in a stream. Note that it is the kth largest element in the sorted order, not the kth distinct element. Implement KthLargest class: KthLargest(int k, int[] nums) Initializes the object with the integer k and the stream of integers nums....
Given an integer array `nums` and an integer `k`, return the `k-th` largest element in the array. Note that it is the `k-th` largest element in the sorted order, not the `k-th` distinct element. Can you solve it without sorting?#...
