The Moroccan Spices Box Set Puzzle
In the heart of the medina of Marrakech, you will find one of the largest and most colourful souks in Morocco. In this souk, you will find merchants selling traditional clothing, multicoloured carpets, pottery, jewellery, antiques, lanterns, spices, etc. On…
Recursive vs. Iterative Algorithm – Q&A
Question 1[2 marks] For this question, we are looking at an algorithm used to implement the divisibility rule for 3 which states that: A number is divisible by 3 if the sum of all its digits is divisible by 3.… The Climbing Stairs Puzzle
Imagine a staircase with n steps. As you are climbing up this staircase, you either climb one or two steps at a time. The aim of this computing puzzle is to find out, using an algorithm, in how many distinct…
Divisibility Rules
For this challenge we will investigate a range of algorithms used to apply some of the most common divisibility rules. We will first focus on the divisibility rule of 3 to introduce the concept of recursion. A divisibility rule is…
Recursive vs. Iterative Palindrome Check
For this challenge we will investigate two algorithms used to find out if a word is a palindrome or not. The first algorithm will use an iterative approach, the second algorithm will use a recursive approach. Iterative Approach An iterative…
The Social Network
Six Degrees of Separation The Six degrees of separation is an idea that was originally set out by Frigyes Karinthy in 1929 and that can be applied to Social Networks such as Facebook. It is based on the idea that…
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
