Challenge: Find k Smallest Elements in the Array

Given a array and a number "k" write a function that returns the first "k" smallest elements using a Heap.

Problem Statement

Implement a function findKSmallest(int arr[], int size, int k) that takes an unsorted integer array as input and returns the “k” smallest elements in the array using a Heap. The minHeap class is prepended to this exercise, so feel free to use it! Have a look at the illustration given for a clearer picture of the problem.
