Code Challenges

If you would like to search through the code challenges, I would recommend clicking on the repositories button next to "Overview" in the top row of button and using the search bar there. You can search using the name of the challenge, the difficulty Easy, Medium, Hard, the language such as Python, Rust, C, Java, or by searching for a key word to do with the challenge such as Recursion or Game.

Challenge Repository Languages Difficulty Description
Factorial Finder Click Here Python, Rust Easy The Factorial of a positive integer, n, is defined as the product of the sequence n, n-1, n-2, ...1 and the factorial of zero, 0, is defined as being 1. Solve this using both loops and recursion.
Speed Tracker Click Here Python Easy Create a program that takes a time for a car going past a speed camera, the time going past the next one and the distance between them to calculate the average speed for the car in mph. The cameras are one mile apart.
Thief Click Here Python Easy Design and write a program that displays all the possible combinations for any four numerical digits entered by the user. The program should avoid displaying the same combination more than once.
Classification Click Here Python Easy A simple classification system asks a series of Yes/No questions in order to work out what type of animal is being looked at.
Fruit Machine Click Here Python Easy Write a program to simulate a Fruit Machine that displays three symbols at random from Cherry 🍒, Bell 🔔, Lemon 🍋, Orange 🍊, Star ⭐, Skull 💀.
Unit Converter Click Here Python Easy Converts various units between one another. The user enters the type of unit being entered, the type of unit they want to convert to and then the value. The program will then make the conversion .

  • Ordering Public

    Create a program that allows entry of 10 numbers and then sorts them into ascending or descending order, based on user input. The user can input a word or string, and it arranges the string into alphabetical order. E.g. My Rabbit would be shown as “abbimty “. (Punctuation placement is not essential)

  • CasearCipher Public

    Implement a Caesar cipher, both encoding and decoding. The key is an integer from 1 to 25. This cipher rotates the letters of the alphabet (A to Z). The encoding replaces each letter with the 1st to 25th next letter in the alphabet (wrapping Z to A). So key 2 encrypts “HI” to “JK”, but key 20 encrypts “HI” to “BC”.
