WebApr 6, 2014 · There's no reason why a heap implemented in an array has to leave the item at index 0 unused. If you put the root at 0, then the item at array [index] has its children at array [index*2+1] and array [index*2+2]. The node at array [child] has its parent at array [ (child-1)/2]. Let's see. WebJan 29, 2024 · At the run-time, there is a chance of arising heap pollution that will cause ClassCastException. Heap pollution means the bad data in the heap memory. Here bad data is an object of type X but an object of type Y is expected and it will throw ClassCastException at runtime. Lets understand the heap pollution with program:

What is a Heap? A heap implements a binary tree structure. A binary tree consists of a hierarchy of nodes where each parent node always has two child nodes. In a max heap, the node with the largest value sits on top. WebThere are 2 important features of a Binary Heap. One, it is a complete Binary Tree, which means it can be stored as an Array.
