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. |
