In our Enigma – mission X challenge, we looked at how the Enigma machine was used by the Germans during WWII to encrypt radio communications and how code breakers were assigned the job to crack the code of the Enigma…

Enigma Daily Settings Generator
Before attempting this challenge, you should familiarise yourself with the Enigma machine by completing the Enigma Mission X challenge. Code Books were used by the Germans to list all the settings needed to set up the Enigma machines before starting…
Enigma – Mission X Challenge
Dear code breaker, I am contacting you from Bletchley Park as we are intercepting an increased volume of encrypted radio signals. We are working day and night to break the enigma codes that the German Navy are updating every day.…
Enigma Machine Emulator
The Enigma machines are a series of electro-mechanical rotor cipher machines. The first machines were invented at the end of World War I by German engineer Arthur Scherbius and were mainly used to protect commercial, diplomatic and military communication. Enigma…
Stopping Distance Calculator
In this challenge, we will write a Python program to estimate the total stopping distance of a vehicle based on its speed. The stopping distance consists of two components. The first component is the reaction distance covered by the vehicle…
Binary Permutations Challenge
Did You Know?Everything that is stored on a computer is stored as binary code. Binary code is made of bits (0 or 1). We often use Bytes to store data. A Byte is made of eight bits and can be…
Complementary Colours Algorithm
Complementary colours are pairs of colours which, when combined or mixed, cancel each other out by producing a grayscale colour like white or black. When placed next to each other, they create the strongest contrast for those two colours. Complementary…
My Weekly Timetable
A school timetable is displayed as a 2D table consisting of 5 rows (for each day of the week) and 5 columns (number of lessons in a day). Such a table can be stored in a computer program using a…
Colour Difference Formula
RGB Colour CodesDid you know that every colour on the screen can be represented using an RGB code (Red, Green, Blue) code. This code consists of three numbers between 0 and 255, indicating how much red, green and blue are…
Cell Phone Trilateration Algorithm
Mobile phone tracking is a process for identifying the location of a mobile phone, whether stationary or moving. Localisation may occur either via multilateration of radio signals between several cell towers and the phone, or simply via GPS. Mobile positioning is used by telecommunications companies to approximate…
