## How do you create a heap?

Step 1 − Create a new node at the end of heap. Step 2 − Assign new value to the node. Step 3 − Compare the value of this child node with its parent. Step 4 − If value of parent is less than child, then swap them.

## How does a min heap work?

A Min-Heap is a complete binary tree in which the value in each internal node is smaller than or equal to the values in the children of that node. Mapping the elements of a heap into an array is trivial: if a node is stored a index k, then its left child is stored at index 2k + 1 and its right child at index 2k + 2.

## What is heap and its types?

A Heap is a special Tree-based data structure in which the tree is a complete binary tree. Generally, Heaps can be of two types: Max-Heap: In a Max-Heap the key present at the root node must be greatest among the keys present at all of it’s children.

## What is heap tree explain with example?

A heap is a tree-based data structure in which all the nodes of the tree are in a specific order. For example, if is the parent node of , then the value of follows a specific order with respect to the value of and the same order will be followed across the tree.
