Did you know you can estimate the value of Ï€ (pi) using probability and number theory? This challenge explores a surprising mathematical relationship: The probability that two randomly chosen integers are coprime, is equal to Coprime numbers? Two numbers are…
In this tutorial, we will learn how to animate a character in Python using the Pygame library and a spritesheet. Instead of loading lots of separate images to animate our main sprite/character, we will use one single image containing multiple…
A high school teacher needs your help! They have been asked to organise a full set of registers for students to take part in some extracurricular activities organised by the school. There are 100 students in the year group, and…
The Goldbach Conjecture is an unproven mathematical rule, proposed by Christian Goldbach in 1742, stating that every even integer greater than 2 is the sum of two prime numbers. Despite verification by computers up to 4 x 1018, no formal…
The Basel Problem In the 17th century, mathematicians became fascinated by an infinite series known as the Basel Problem. The question was simple to state but extremely difficult to solve: What is the exact value of the following infinite series?…
Passwords are the first line of defence protecting our online accounts. But how secure is your password really? In this Python challenge we will create a program that estimates how long it would take for a hacker to guess a…
Choosing a sport can be tricky! Some people enjoy team sports, others prefer individual sports. Some love being outdoors, while others prefer indoor activities. In this Python challenge, you will create a simple sports adviser program that asks the user…
One of the most powerful ways to understand Big O Notation is to compare two different ways of solving the same problem. Duplicate Detection Challenge? The aim of a duplicate detection algorithm is to determine whether a list of values…
When learning about algorithms, one of the most important ideas in computer science is the Big O Notation. It helps us measure how efficient an algorithm is — especially as the size of the problem gets bigger. To introduce this…
One of the fun things you can do in BBC BASIC is create frame-based animations using custom characters. In this tutorial, we will explain how the following program makes a stickman walk from left to right across the screen. Here…
