Space Invaders – 3D Pixel Art
In this blog post we will use Glowscript to create a 3D animation of a space invader. 2D Graphics used in retro arcade games consist of pixels. A 2D graphic can be described as a grid of pixels of different…
London Underground – Journey Planner
The aim of this Python challenge is to investigate how graphs can be used in Computer Science and investigate the key algorithms used when manipulating graphs in Python such as an algorithm to find the shortest path between two nodes…
Insertion Sort Algorithm
The Insertion sort algorithm is one of the key sorting algorithms used in Computer Science. To start with, the algorithm considers the first value of a list as a sorted sub-list (of one value to start with). This iterative algorithm…
Bubble Sort Algorithm
The Bubble sort algorithm is one of the key sorting algorithms used in Computer Science. It is a fairly simple algorithm to implement and is particularly useful when you need to find the top x values of a list. The…
Backtracking Maze – Path Finder
The purpose of this Python challenge is to demonstrate the use of a backtracking algorithm to find the exit path of Maze. Backtracking Algorithm A backtracking algorithm is a recursive algorithm that attempts to solve a given problem by testing…
Backtracking Algorithm – Sudoku Solver
The purpose of this Python challenge is to demonstrate the use of a backtracking algorithm to solve a Sudoku puzzle. Did You Know? The objective of a Sudoku puzzle is to fill a 9×9 grid with digits so that each…
Backtracking Algorithm – Magic Square Solver
The purpose of this Python challenge is to demonstrate the use of a backtracking algorithm to solve a Magic Square puzzle. Did You Know? A 3×3 magic square is an arrangement of the numbers from 1 to 9 in a…
Food Chain Game Using Python
Learning Objectives? In this set of Python challenges we will investigate the use of two data structures used in programming to represent data: We will use an array/list to represent a food chain. We will use a graph to represent…
