What is printed to the console when the following code is executed?

public class HeapifyTest {
    public static void main(String[] args) {
        int[] heap = {5, 8, 12, 15, 3}; // 0-indexed min heap (except element 3 is out of place)
        
        int child = 4;  // value 3
        while(child > 0) {
            int parent = (child - 1) / 2;
            if(heap[child] < heap[parent]) {
                int temp = heap[child];
                heap[child] = heap[parent];
                heap[parent] = temp;
                child = parent;
            } else {
                break;
            }
        }
        
        for(int i = 0; i < heap.length; i++){
            System.out.print(heap[i] + " ");
        }
    }
}
