Work Life Balance (HTML, CSS & JS Challenge)
When your browser displays a webpage on screen it uses 3 different programming languages called HTML, CSS and JavaScript. We call the combination of these three languages “client-side web technologies”. Each of the three language has its own syntax and…
The Birthday Paradox
The birthday paradox is based on a counter-intuitive fact that in any class of 23 students or more, there is a higher probability of having at least two students sharing the same bithday. Considering that there are 366 different possible…
Elastic Collision in a Pool Game
A range of video games use elastic collision formulas to predict the change of velocity of two objects when a collision occurs. Elastic collision occurs when two objects are colliding and the total kinetic energy of the two objects remains…
The Monty Hall Problem
The Monty Hall problem is a counter-intuitive brain teaser based on probabilities. This puzzle is named after Monty Hall, the TV presenter of “Let’s Make a Deal”, an American TV show (known as “Deal or No Deal” in the UK)…
Denary to Binary Conversion Algorithm
In this challenge, we are going to write al algorithm to convert a decimal (aka Denary) number between 0 and 255 into binary using 1 Byte (=8 bits). Before attempting this challenge you may practise your denary to binary conversion:…
Software Crosswords
A computer system consists of both hardware (the physical components of the computer) and software: the programs that run on this hardware. There are three main categories of software: Operating Systems: software that controls the computer hardware: The operating system…
