# 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.

&#x20;

**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
```

&#x20;

**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.
