public class KthLargest extends java.lang.Object
703 - Kth Largest Element in a Stream.

Easy

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.

Implement KthLargest class:

  • KthLargest(int k, int[] nums) Initializes the object with the integer k and the stream of integers nums.
  • int add(int val) Appends the integer val to the stream and returns the element representing the kth largest element in the stream.

Example 1:

Input

 ["KthLargest", "add", "add", "add", "add", "add"] 
 [[3, [4, 5, 8, 2]], [3], [5], [10], [9], [4]]

Output: [null, 4, 5, 5, 8, 8]

Explanation:

 KthLargest kthLargest = new KthLargest(3, [4, 5, 8, 2]); 
 kthLargest.add(3); // return 4 
 kthLargest.add(5); // return 5 
 kthLargest.add(10); // return 5 
 kthLargest.add(9); // return 8 
 kthLargest.add(4); // return 8

Constraints:

  • 1 <= k <= 104
  • 0 <= nums.length <= 104
  • -104 <= nums[i] <= 104
  • -104 <= val <= 104
  • At most 104 calls will be made to add.
  • It is guaranteed that there will be at least k elements in the array when you search for the kth element.
