Digit Sum Algorithm
For this challenge, we are going to write a function to calculate the digit sum of a given number. The digit sum of a number corresponds to the sum of all the digits of this number. For instance the digit…
The Uppercase Challenge
The aim of this challenge is to rewrite the upper() function that is used in Python to convert the case of a string to uppercase. This is how the upper() function works in Python: string = "Hello world!" upString =…
Finding the Factors of… (LMC Challenge)
The aim of this challenge is to write a program using LMC to list all the factors of a given number. The program will: Ask the user to enter a positive number (e.g. 12) Display all the factors of this…
The Fish and Chips Puzzle
To complete this puzzle, we first need to investigate the following lines of code: a = "chips" b = "fish" print(a + " and " + b) What would be the output of this code if you executed it? Your…
Cryptography Challenge
Cryptography, or cryptology is the practice and study of techniques for secure communication. Cryptography relies on using more or less complex encryption algorithms to encode a readable message (plaintext) into a collection of characters (ciphertext) that is hard to decipher…
Back to the Future – Time Machine
In this Python challenge, we are going to investigate how to manipulate dates in Python using the datetime library. The aim of this challenge is to write a piece of code to control the Time Machine (aka Flux Capacitor) found…
Cumulative Elevation Gain Calculator
In mountaineering, running or cycling the cumulative elevation gain (aka total ascent) refers to the sum of every gain in elevation throughout an entire trip. Note that when calculating this elevation gain, elevation losses are not counted in this measure.…
Maths Fraction Hack Algorithm
In this challenge we are going to use an easy hack to quickly compare two fractions without having to calculate their decimal value. For instance, can you quickly tell which of the following two fractions is bigger? Fraction Hack: The…
