# K Largest Elements
# Send Feedback
# You are given with an integer k and an array of integers that contain numbers in random order. Write a program to find k largest numbers from given array. You need to save them in an array and return it.
# Time complexity should be O(nlogk) and space complexity should be not more than O(k).
# Order of elements in the output is not important.
# Input Format :
# Line 1 : Size of array (n)
# Line 2 : Array elements (separated by space)
# Line 3 : Integer k
# Output Format :
# k largest elements
