1. We want to get K = 3 smallest items from the array and using Max heap data structure. So this is how to think about it. 1. We take first K items put it into Max Heap: 5 / \ 4 1 2. Then we move forward to next element '2' in the array, we check Whether 2 is smalle...
As we can see above, we use anindicatorto figure out the last item index added to the array. But before we continue, we need to remember thatthe array index starts from zero, but we assume the index starts from one in a heap. We can find the index of left and right children using...

. 3. implementation in java let’s start with a simple class that represents our min-max heap: public class minmaxheap<t extends comparable<t>> { private list<t> array; private int capacity; private int indicator; } as we can see above, we use an indicator to figure out the last ...
