Kth largest element in a stream
Medium Accuracy: 14.89% Submissions: 249 Points: 4

Given an input stream arr[] of n integers, find the kth largest element for each element in the stream.

 

Example 1:

Input:
k = 4, n = 6
arr[] = {1, 2, 3, 4, 5, 6}
Output:
-1 -1 -1 1 2 3
Explanation:
k = 4
For 1, the 4th largest element doesn't
exist so we print -1.
For 2, the 4th largest element doesn't
exist so we print -1.
For 3, the 4th largest element doesn't
exist so we print -1.
For 4, the 4th largest element is 1.
For 5, the 4th largest element is 2.
for 6, the 4th largest element is 3.

Example 2:

Input:
k = 1, n = 2
arr[] = {3, 4}
Output:
3 4

 

Your Task:
You don't need to read input or print anything. Your task is to complete the function kthLargest() which takes 2 Integers k, and n and also an array arr[] of size n as input and returns the kth largest element in the stream.

 

Expected Time Complexity: O(n)
Expected Auxiliary Space: O(n)

 

Constraints:
1 <= k <= n <= 105
1 <= arr[i] <= 105
