636.Kth Largest Element in an Array 1.Problem Find thekth largest element in an unsorted array. Note that it is the kth largest element in the sorted order, not the kth distinct element. 题意很简单,找到一个一维数组中的第K大的数并返回。数组中第K大的数也是面试中经常考察的问题。现在就借L...
You may assume k is always valid, 1 ≤ k ≤ array's length. 寻找一个数组中第k大的数。 1、建立一个大小为k的数组,每次维护这个数组,属于暴力做法。 publicclassSolution {publicintfindKthLargest(int[] nums,intk) {intlen =nums.length;int[] result =newint[k];for(inti = 0; i < k ; ...
public: int findKthLargest(vector<int>& nums, int k) { int left = 0,right = nums.size(); while(true){ int pos = partition(nums, left, right); if(pos == k-1) return nums[pos]; if(pos > k-1) right = pos; else left = pos+1; } } int partition(vector<int>& nums,int ...
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. ...
