215. Kth Largest Element in an Array 题目: 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 vali...
215. Kth Largest Element in an Array 题目链接:https://leetcode.com/problems/kth-largest-element-in-an-array/?tab=Description 题目大意:给定一个未排序的数组,找出数组中第k大的数。举个例子数组nums为[3,2,1,5,6,4],k=2,则返回5. 思路:(1) 对数组进行降序排序后返回数组的第k-1个元素 (2)...
代码的话,分区可以采取双指针,i前边始终存比分区点大的元素。 publicintfindKthLargest(int[]nums,intk){returnfindKthLargestHelper(nums,0,nums.length-1,k);}privateintfindKthLargestHelper(int[]nums,intstart,intend,intk){inti=start;intpivot=nums[end];//分区点//将 i 的左半部分存比分区点大的数...
