In this assignment you are to write a Python program to implement heapsort algorithm & apply it on a provided list.

You are provided with the template in which you must:

$(1)$ implement Phase II of a heapsort algorithm:

$(1\mathrm{.}1)$ function that sifts down the value of the heap root to a correct position, and

$(1\mathrm{.}2)$ function that finds the largest child of a given heap node.

Your program must:

$$ take a file containing input list of values as a command line argument and print the original list,

$$ create a heap form a given list of values and print created heap,

$$ sort given list using heapsort algorithm $(1),$ and print sorted list.

Following is the output of the program run applied on a provided test file:

Together with your source code include a separate file Namingformat.py with your information as the values of the

following variables:

myName $=$ 'first$\_$name last$\_$name'

myTechID $=\text{'}0000000\text{'}$

myTechEmail $=$ 'abc$123\text{'}$ #only your email id omit @latech.edu

You must properly cite the sources if you use any help from peers or any code$/$ideas from online resources. Failure to do

so will be treated as a plagiarism. Properly citing the sources should be done as a comment in your code. Some examples:

Original list: $[10,30,-100,50,20,30,-40,70,5,50]$

Heapified list:

Heap size: $10.$

Heap capacity: $10.$

Elements of heap:

Value: $70$ at index: $0$

Value: $50$ at index: $1$

Value: $30$ at index: $2$

Value: $30$ at index: $3$

Value: $50$ at index: $4$

Value: $-100$ at index: $5$

Value: $-40$ at index: $6$

Value: $10$ at index: $7$

Value: $5$ at index: $8$

Value: $20$ at index: $9$

Sorted list: $[-100,-40,5,10,20,30,30,50,50,70]$
