How do heaps and binary trees differ from each other?

Heaps and binary trees are both tree-based data structures, but they serve different purposes. A binary tree is a general tree structure where each node has at most two children, while a heap is a specialized tree-based structure that satisfies the heap property, either max-heap or min-heap.

What are the main characteristics of a binary tree?

A binary tree has nodes with at most two children, typically referred to as the left and right child. It can be complete, full, or balanced, and it does not have a specific ordering of values.

Can you explain the heap property?

Sure! In a max-heap, for any given node, the value of that node is greater than or equal to the values of its children. In a min-heap, the value of the node is less than or equal to its children. This property ensures that the highest (or lowest) value is always at the root.

When would you use a heap instead of a binary tree?

Heaps are particularly useful when you need to efficiently access the maximum or minimum element, such as in priority queues. Binary trees are more versatile for general tree operations but may not provide the same efficiency for these specific tasks.
