Once you have your heap structure created, next you must use it as a backing structure to a priority queue. Develop a PriorityQu

saveliy_v [14]

Using the knowledge in computational language in python it is possible to write a code that Develop a PriorityQueue data structure in a file.

<h3>Writting the code in python:</h3>

import sys

class Node:

self.left = None

self.right = None

self.val = key

self.parent = None

class MinHeap:

node1.data, node2.data = node2.data, node1.data

# Function to heapify the node at pos

# If the node is a non-leaf node and greater

# than any of its child

if not self.isLeaf(node):

if (node.data > node.left.data or

node.data > node.right.data):

# Swap with the left child and heapify

Hoods become necessary any time water temperatures drop below:

mestny [16]

Hoods become necessary any time water temperatures drop below: 20°C/68°F.

<h3>Why is it necessary to use Hoods any time water temperatures drop below: 20°C/68°F?</h3>

It is important to use hood so as to adjust the cold temperature, so as to be able to gain heat.

Therefore, hood serves as a covering for the head as well as the neck which has a opening face that prevent cold.
