/**
 * 703. Kth Largest Element in a Stream
 *
 * 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.
 * Your KthLargest class will have a constructor which accepts an integer K and an integer array nums,
 * which contains initial elements from the stream.
 * For each call to the method KthLargest.add, return the element representing the kth largest element in the stream.
 *
 * Example:
 *
 * int K = 3;
 * int[] arr = [4,5,8,2];
 * KthLargest kthLargest = new KthLargest(3, arr);
 * kthLargest.add(3);   // returns 4
 * kthLargest.add(5);   // returns 5
 * kthLargest.add(10);  // returns 5
 * kthLargest.add(9);   // returns 8
 * kthLargest.add(4);   // returns 8
 * Note:
 * You may assume that nums' length ≥ K-1 and K ≥ 1.
