Python fast sorting in less than 128 words

Quick sorting (QuickSort) randomly select an element (called pivot) and position it in its final place, swapping all the elements so that those below the pivot are to its left and those above the pivot to its right.

The operation is called partitioning. For each sub-list (or sub-table), a new pivot is randomly selected and the partitioning operation is repeated. This process is repeated recursively, until all items are sorted.

The partitioning consists of:

  • swap the pivot with the last element of the subtable
  • place at the top of the sub-table the elements below the pivot
  • move the pivot to the right of the last item moved at the beginning of the table (the other elements being higher than the pivot).
Example of a partitioning iteration (source wikipedia): Here the pivot is 5
from random import randint

Filius download network simulator and filius mac download

Filius is a network simulation software. Here we explain the filius download and install filius mac os (filius für mac, filius macos) and filius ubuntu (filius linux). Its use is interesting in the context of the "Understanding the functioning of a computer network"

Filius is a network simulation software. Here we explain the filius download and install filius mac os (filius für mac, filius macos) and filius ubuntu (filius linux). Its use is interesting in the context of the “Understanding the functioning of a computer network”. This article briefly describes the installation of the software and the configuration on a linux/Mac bone post.

Step 1 filius download: I downloaded the filius software

It is available on the site in German: https://www.lernsoftware-filius.de/HerunterladenI a
lso created a link translated by google that is here: http
s://translate.google.com/translate?hl=fr&sl=de&u=https://www.lernsoftware-filius.de/Herunterladen&prev=search

For MAC OS I downloaded the ZIP file

Step 2 filius mac download – Filius linux : command to setup filius

On MAC OS or linux you have to start a terminal and go into the directory that contains the downloaded .zip file.

On MAC OS I typed the command

Downloads cd/ 

I’ve dezipped the archive in my user directory

unzip filius-1.7.4.zip -d

I executed the following commands to return to my user directory and view the contents of the package that was dezippé.

Cd 
cd filius
Ls

I get the content of the directory displayed

 Changelog.txt GPLv2.txt hilfe
 Einfuehrung_Filius.pdf GPLv3.txt img
 Filius.command Introduction_Filius.pdf lib
 Filius.exe config tmpl
 Filius.sh filius.jar

Filius is a program compiled in Java in the Filius.jar archive.
For MAC OS and Linux there is a File Filius.command that allows to launch the program via the JVM.

The file contains the following commands if viewed via the cat command

Filius.command cat

Script filius mac download – The script displayed is:

'!/bin/bash'
# 
This script is meant as supportive start script for
UNIX-like systems, e.g., Linux or Mac OS X
#
echo "Possible parameters:"
echo -e "-t-l'twrite log file 'filius.log'"
echo -e ''t-wd <path>'tchange base directory for working directory '.filius'"</path>
Echo

change to directory where filius is installed
relpath-$0
cd $'relpath%'basename $0'

Start filius
java -jar filius.jar $ @

change back to former directory
Cd - 'dev/null'

The important command in this script is java-jar filius.jar $that. It is used to launch the Filius software via the JVM. We find that it is possible to start the script with the setting -l to logue in a file and -w to change the default work directory.

Step 3: Shortcut to the filius macos, filius ubuntu or filius linux

I’ve added the running rights to the script via the chmod’x command to allow it to run

chmod x Filius.command

Step 4 run filius mac download: I execute Filius via the command

./Filius.command

Filius runs and starts, note that the ‘no’ allows you to block the terminal

On MAC OS it is possible after executing the previous command chmod x Filius.command to start Filius via the graphical interface in finder.

Step 5: Finder in macos

I went into Finder in the filius directory in which the downloaded archive is unzipped. I clicked twice on Filius.command and I get the message

It’s impossible to open Filius.command because this app comes from an unidentified developer.

Step 6: filius.command

I went to System Preference – General Tab Security and Privacy. In the second part it is noted “Allow downloaded applications from:” and we see “The opening of Filius.command” is blocked because the application comes from an unidentified developer.

I clicked “Open anyway” and then “Open”

The Filius app can then be started from the Finder by clicking “Filius.command.”

Step 7 filius mac download : To add a shortcut in the Dock MAC OS to filius you need to create a .app with the Filius.command script

I used the appify script of Thomas Aylott, here https://gist.github.com/mathiasbynens/674099.

You have to open a text editor and I pasted the code of the script in the link above by saving it in a appify.sh file. It’s also possible to do it online with nano for example and I then pasted a shortened version of the script:

nanoappify.sh
'!/usr/bin/env bash

APPNAME-$$-2:$(basename "${1}" '.sh')
DIR"$-APPNAME.app/Contents/MacOS";

If[ -a "${APPNAME}.app" ]; Then
    echo "$-PWD/$-APPNAME.app already exists :(";
    Exit 1;
fi;

mkdir -p "$-DIR";
cp "${1}" "$-DIR/$-APPNAME";
chmod 'x '$'DIR'/$'APPNAME';

echo "$-PWD/$APPNAME.app";

After recording via Ctrl-X and then “Y” you must allow the script to run via the command:

chmod x appify.sh

The next order converts Filius.command to Filius.app

./appify.sh Filius.command "Filius"

Message confirms the creation of Filius.app

I then moved the .app to Filius.app in my user directory and then copied the entire Filius directory recurringly into the mac os package created via the 2 commands.

mv Filius.app/
cp -r - Filius.app/Contents/MacOS/

The app is now in the main user’s directory (it can be accessed via finder via the home icon). It can then be slid to the Dock Mac Bone.

How to change the language used by Filius:

If you want to re-post the menu to choose the language in filius just erase the settings recorded by filius via the terminal command:

rm -r.filius

Sorting by selection in Python

tab[111, 34, 22, 55, 4, 2, 1, 77]

for i in range (0,len(tab)-1):
	min i
	for j in range (i-1,len(tab):c)
		if tab<tab[j]:></tab[min]:>
			min - J
	if (min!
		tmp - tab[i]
		ta[i]b-tab[min]
		tab[min] - tmp

print (tab)

If we consider the "if tab" comparison operation<tab" et n la taille du tableau. et="" n="[j]" la=""[min] taille="" du=""></tab" et n la taille du tableau.>

If i -0 -0 (n-1) comparisons

If i – 1 – (n-2) comparisons

… If i 'n-2' – 1 comparison

or n – (n-1) comparisons

So the loop for i in range (0,len(tab)-1): runs n-1 times

The for j in range loop (i-1,len(tab):runs (n-(i-1) – 1) times

The complexity in the number of comparisons is equal to the sum of the following n-1 terms (i – 1, … i – n-1)

C – (n-2) -1 – (n-3) -1…..-1-0 -1-0 -(n-1)–(n-2)-…-1 -n.(n-1)/2 (this is the sum of the entire first n-1).

The complexity in the number of comparisons is in the order of n2, one writes O(n2).

The calculation of the TCP control amount explained in more than 128 words

The TCP (checksum) control sum, intended for package integrity control, uses a pseudo-header that consists of the source IP of origin, destination, reserved file name (identified by 0000,0000), protocol (x06) and the length of the header Tcp.

The binary addition is based on the rules:

  • Rule 1: 0 – 0 – 0;
  • Rule 2: 1 – 0 – 1;
  • Rule 3: 1 – 1 – 0 with carry of 1;
  • Rule 4: 1 – 1 – 1 – 1 with carry of 1.

To add up several binary numbers you have to proceed in pairs and carry out postponements.

Python Strings in more than 128 words

In python the strings of characters (Strings) are surrounded by simple quotation marks or double quotation marks, both notations are equivalent. The print feature () allows you to display the number of characters on the screen.

print ("Hello") #notation double quotes and display
print ('Hello') #notation simple quotes
a - "Test" #assignation           

Python offers methods that can be used on String-type objects

a - "Hello, World!"
print(a.upper))) #retourne the chain of character in capital letters   
a - "Hello, World!"
print(a.lower))) #retourne the string of character in tiny
txt - "Hello the world"
x - txt.find ("world")
print(x) #retourne the position of the word you are looking for
a - "Hello, the world!"
(a.replace) #Remplace a chain of character
a - "Hello"
b - "World"
c - a -b
print(c) #Affiche the concatenation of the two character chains
Python gives belonging operators who are used to test whether a sequence is presented in an object:
x - 'Apple and banana'
print ("banana" in x) #Affiche True
print ("pear" not in x) #Affiche True
print ('cherry' in x) #Affiche False
