GCSE/A-Level Coding Challenges Booklet's repositories
CreditCardValidator
Takes in a credit card number from a common credit card vendor (Visa, MasterCard, American Express, Discoverer) and validates it to make sure that it is a valid number (look into how credit cards use a checksum).

CasearCipher
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”.
Classification
A simple classification system asks a series of Yes/No questions in order to work out what type of animal is being looked at. Carry out some simple research on classification trees, then write a program to help the user decide between the following: horse, cow, sheep, pig, dog, cat, lion, tiger, whale, dolphin, seal, penguin, ostrich, sparrow, spider, ant, bee, wasp, termite, octopus, squid.
CodeChallengeTemplate
A GitHub repository template for creating the code challenges. Includes, Issues templates, Topics, Code of Conduct, Contributing guidelies, and funding details. This is for easy set up of code challenges.
FactorialFinder
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.
FruitMachine
Write a program to simulate a Fruit Machine that displays three symbols at random from Cherry :cherries:, Bell :bell:, Lemon :lemon:, Orange :orange:, Star :star:, Skull :skull:.
Ordering
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)
SpeedTracker
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
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.
UnitConverter
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.
Hack-proof
Create a program that will only open a text document if the correct password is entered. The user should choose the username and password first and it should also verify the password before allowing it.
Palindromes
Write a program that checks if a string entered by the user is a palindrome. A palindrome is a word that reads the same forwards as backwards like “racecar" or "hannah".
