KthLargest(int k, int[] nums)Initializes the object with the integerkand the stream of test scoresnums. int add(int val)Adds a new test scorevalto the stream and returns the element representing thekthlargest element in the pool of test scores so far. Example 1: Input: ["KthLargest",...
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: 4 Note: You may ...
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. 寻找一个数...
Kth Largest Element in an Array 数组中第k大的数字 开始的时候我的脑子里产生了很多天马行空的想法,比如用一个queue去重新存放顺序之类的。但是那显然是不合理且乱糟糟的。kth largest,就是一个排序问题。这里又一次用到了分治法,而且用到了快速排序里的左右互相交换的方法。左右互相交换,可以保证作为pivot的...
class KthLargestElementQuickSelect { static Random random = new Random(); public int findKthLargest3(int[] nums, int k) { int len = nums.length; return select(nums, 0, len - 1, len - k); } private int select(int[] nums, int left, int right, int k) { ...
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. ...
