Kth Largest Element in a Stream</a></h2><h3>Easy</h3><hr><p>Design a class to find the <code>k<sup>th</sup></code> largest element in a stream. Note that it is the <code>k<sup>th</sup></code> largest element in the sorted order, not the <code>k<sup>th</sup></code> distinct element.</p> |

| 3 | +<p>Implement <code>KthLargest</code> class:</p> |
| 4 | + |
| 5 | +<ul> |
| 6 | + <li><code>KthLargest(int k, int[] nums)</code> Initializes the object with the integer <code>k</code> and the stream of integers <code>nums</code>.</li> |
| 7 | + <li><code>int add(int val)</code> Appends the integer <code>val</code> to the stream and returns the element representing the <code>k<sup>th</sup></code> largest element in the stream.</li> |

| 13 | +<pre> |
| 14 | +<strong>Input</strong> |
| 15 | +["KthLargest", "add", "add", "add", "add", "add"] |
| 16 | +[[3, [4, 5, 8, 2]], [3], [5], [10], [9], [4]] |
| 17 | +<strong>Output</strong> |
| 18 | +[null, 4, 5, 5, 8, 8] |
| 19 | + |
| 20 | +<strong>Explanation</strong> |
| 21 | +KthLargest kthLargest = new KthLargest(3, [4, 5, 8, 2]); |
| 22 | +kthLargest.add(3); // return 4 |
| 23 | +kthLargest.add(5); // return 5 |
| 24 | +kthLargest.add(10); // return 5 |
| 25 | +kthLargest.add(9); // return 8 |
| 26 | +kthLargest.add(4); // return 8 |

| 31 | + |
| 32 | +<ul> |
| 33 | + <li><code>1 <= k <= 10<sup>4</sup></code></li> |
| 34 | + <li><code>0 <= nums.length <= 10<sup>4</sup></code></li> |
| 35 | + <li><code>-10<sup>4</sup> <= nums[i] <= 10<sup>4</sup></code></li> |
| 36 | + <li><code>-10<sup>4</sup> <= val <= 10<sup>4</sup></code></li> |
| 37 | + <li>At most <code>10<sup>4</sup></code> calls will be made to <code>add</code>.</li> |
| 38 | + <li>It is guaranteed that there will be at least <code>k</code> elements in the array when you search for the <code>k<sup>th</sup></code> element.</li> |
