## What is level order traversal of heap?

The level order traversal of the heap is 10, 8, 5, 3, 2. Two new elements ‘1’ and ‘7’ are inserted into the heap in that order. The level order traversal of the heap after the insertion of the elements is. 10, 8, 7, 5, 3, 2, 1. 10, 8, 7, 2, 3, 1, 5.

## What is level order traversing?

(algorithm) Definition: Process all nodes of a tree by depth: first the root, then the children of the root, etc. Equivalent to a breadth-first search from the root. See also postorder traversal, preorder traversal, tree traversal, Cupif-Giannini tree traversal, level (1).

**What is the level order traversal explain with examples?**

The level order traversal means traversing left to right level-wise. Level order traversal of the following example turns to be: 2, 7, 5, 2, 6, 9, 5, 11, 4. The level order traversal is defined as follows: Visit the root.

**How do you traverse a heap?**

Based on this, we could construct the following algorithm:

- Create a heap (another one)
- Insert the root of the original heap into the new heap.
- While the new heap has elements: Remove minimum from the heap. Output that element. Add the children of that element in the original heap, if it has any, to the new heap.

### Is Level order traversal same as BFS?

Level Order traversal is also known as Breadth-First Traversal since it traverses all the nodes at each level before going to the next level (depth). The last level of the tree is always equal to the height of the tree.

### Is BFS a level order?

Level Order traversal is also known as Breadth-First Traversal since it traverses all the nodes at each level before going to the next level (depth). The last level of the tree is always equal to the height of the tree. The last level of the tree should contain at least one Node.

**Why is it called Heapify procedure?**

HEAPIFY is an important subroutine for manipulating heaps. Its inputs are an array A and an index i into the array. When HEAPIFY is called, it is assumed that the binary trees rooted at LEFT(i) and RIGHT(i) are heaps, but that A[i] may be smaller than its children, thus violating the heap property (7.1).

**What is the level Order of the heap?**

The level-order traversal of the heap is: 10, 8, 5, 3, 2. Two new elements 1 and 7 are inserted into the heap in that order. The level-order traversal of the heap after the insertion of the elements is:

#### How is level order traversal used in a tree?

Trees can also be traversed in level order, where we visit every node on a level before going to a lower level. This search is referred to as level order traversal or Breadthâ€“first search (BFS), as the search tree is broadened as much as possible on each depth before going to the next depth.

#### How to print the level Order of a tree?

There are basically two functions in this method. One is to print all nodes at a given level (printGivenLevel), and other is to print level order traversal of the tree (printLevelorder). printLevelorder makes use of printGivenLevel to print nodes at all levels one by one starting from root.

**How to check if a tree is a heap?**

Recommended: Please try your approach on {IDE} first, before moving on to the solution. We need to check whether each non-leaf node (parent) satisfies the heap property.
