Description You are working for Macrohard company in data structures department. After failing your previous task about key insertion you were asked to write a new data structure that would be able to return quickly k-th order statistics in the array
For the k-th number, we all should be very familiar with it. Of course,to kiki it is also simple. Now Kiki meets a very similar problem, kiki wants to design a container, the container is to support the three operations. Push: Push a given element e
Find the kth largest element in an unsorted array. Note that it is the kth largest element in the sorted order, not the kth distinct element. For example, Given [3,2,1,5,6,4] and k = 2, return 5. Note: You may assume k is always valid, 1 ≤ k ≤ array'
Find the kth largest element in an unsorted array. Note that it is the kth largest element in the sorted order, not the kth distinct element. Example 1: Input: [3,2,1,5,6,4] and k = 2 Output: 5 Example 2: Input: [3,2,3,1,2,4,5,5,6] and k = 4 Output:
http://ac.jobdu.com/problem.php?pid=1534 给定两个整型数组A和B.我们将A和B中的元素两两相加可以得到数组C.譬如A为[1,2],B为[3,4].那么由A和B中的元素两两相加得到的数组C为[4,5,5,6].现在给你数组A和B,求由A和B两两相加得到的数组C中,第K小的数字. 对于每个测试案例,输入的第一行为三个整数m,n, k(1<=m,n<=100000, 1<= k <= n *m):n,m代表将要输入数组A和B的长度. 显然直接枚举K
题目:给定一个一维数组,如[1,2,4,4,3,5],找出数组中第k大的数字出现多少次. 例如:第2大的数是4,出现2次,最后输出 4,2 function getNum(arr, k){ // 数组排序->从大到小 arr.sort((a, b)=>{ return b-a; }); let uniqarr = Array.from(new Set(arr)); // 数组去重 let tar = uniqarr[k-1]; // 找到目标元素 let index = arr.indexOf
