Given an array Arr of N positive integers, find Klargest elements from the array. The output elements should be printed in decreasing order.
Example 1:
Input:
N = 5, K = 2
Arr[] = {12, 5, 787, 1, 23}
Output: 787 23
Explanation: 1st largest element in the
array is 787 and second largest is 23.
Example 2:
Input:
N = 7, K = 3
Arr[] = {1, 23, 12, 9, 30, 2, 50}
Output: 50 30 23
Explanation: 3 Largest element in the
array are 50, 30 and 23.
Your Task:
You don't need to read input or print anything. Your task is to complete the function kLargest() which takes the array of integers arr,n and k as parameters and returns an array of integers denoting the answer. The array should be in decreasing order.
Expected Time Complexity: O(N) Expected Auxiliary Space: O(K*logK)
