你可以假设 k 总是有效的,且 1 ≤ k ≤ 数组的长度。 解法: classSolution{public:intfindKthLargest(vector<int>& nums,intk){ priority_queue<int, vector<int>, greater<int>> q;intsz = nums.size();for(inti =0; i < k; i++){ q.push(nums[i]); }for(inti = k; i < sz; i++)...
https://leetcode-cn.com/problems/kth-largest-element-in-an-array 用普通的定长(k)数组作为容器,元素从小到大排列, 遍历列表中的元素,始终维持k个有效元素。 最后取第0个元素就是第k大的元素。 function H(/* int */cap) { this.repo = []; this.cap = cap; this.size = 0; // +1 element ...
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. YourKthLargestclass will have a constructor which accepts an integerkand an integer arraynums, which contains initial elements from the stre...
Given an integer arraynumsand an integerk, returnthekthlargest element in the array. Note that it is thekthlargest element in the sorted order, not thekthdistinct element. Can you solve it without sorting? Example 1: Input:nums = [3,2,1,5,6,4], k = 2Output:5 Example 2: Input:nu...
kthLargest.add(9); // returns 8 kthLargest.add(4); // returns 8 说明: 你可以假设nums的长度≥k-1且k≥ 1。 01 题目解析 保存前k个最大的值,每次进来一个元素A,如果元素A比这k个元素中的最小值还要小就踢出去。那么我们如何保存这k个数呢?
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's length. ...
